What Happens in Tarantulas: The Deadly Cargo: Full Plot Summary

The whole story of Tarantulas: The Deadly Cargo (1977) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

In Ecuador, two reckless money-hungry pilots bribe officials to fly a load of coffee beans into the United States, secretly smuggling three passengers aboard to help pay off their scheme. As the cargo sails north, trouble brews when sacks of beans conceal deadly tarantulas, and a fierce thunderstorm tips the balance—the arachnids break free just as the plane is unsettled by the weather. The three illegal immigrants are trapped in the cargo hold, fighting the spiders with whatever they can find, including shoes and improvised swatters, but the relentless creatures overpower them in the cramped darkness.

In the cockpit, the pilots confront a developing mechanical problem and must execute an emergency landing as they skim over Finleyville, California. Unbeknownst to them, the tarantulas have already escaped into the plane and begin to swarm the cockpit, contributing to the disaster when the craft touches down near Finleyville.

Back on the ground, Finleyville’s emergency teams rush to the wreckage, and a fire erupts at the crash site as the deadly intruders start to spill toward an adjacent orange grove. The fortunate survivors are pulled from the wreckage, yet many begin to exhibit alarming symptoms, confounding the town’s medical community. Dr. Hodgins, [Pat Hingle], struggles to diagnose the unfolding mystery as a bitten bystander suddenly collapses and breaks into old vaudeville songs.

Cindy Beck, [Deborah Winters], and her fiancé Joe Harmon, [Charles Frank], join the effort to untangle the occurrence, while Cindy’s brother Matthew, [Matthew Labyorteaux], discovers a spider and tries to sound the alarm, though his warnings initially fall on deaf ears.

A determined Beck family teaches the town how little is known and how much there is to fear. They learn that the intruders are banana spiders, described with chilling simplicity as, > "the most aggressive and venomous spider in the world".

Mayor Douglas, [Bert Remsen], and Bert Springer, [Claude Akins], rally the community to confront the growing danger as the spiders begin to threaten the town’s livelihood and its people. The bite of another family member proves fatal, underscoring the urgency of finding a cure or a control strategy.

The groaning problem forces a drastic plan: using the buzzing sounds of wasps to disorient the tarantulas, enabling a crew to capture the spiders in buckets of alcohol that kill them. An electrical outage complicates the operation, leaving the team briefly surrounded by the advancing hordes until doors reopen. A resourceful local teacher, [Nancy Burnett], crawls through a window near the roof to guide everyone to safety. When power returns, the town races to finish removing the remaining spiders and protect the area around the orange packaging plant, hoping to prevent a wider disaster.

Tarantulas: The Deadly Cargo Plot Explained: Your Questions Answered

The questions people ask most about Tarantulas: The Deadly Cargo (1977): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q1

Why did the plane crash - was it the spiders or a mechanical problem?

The crash was caused by both factors working together. The pilots discovered a mechanical problem and attempted an emergency landing near Finleyville, but by that time the tarantulas had already escaped into the cockpit and were swarming the pilots. The combination of the mechanical failure and the spider attack made it impossible for the crew to control the aircraft, resulting in the crash.

Foreshadowing: Earlier scenes establish that the tarantulas were already free in the cargo hold during the storm, and they naturally moved toward the cockpit where the pilots sat.

  • plane crash cause
  • tarantulas cockpit
  • mechanical failure
  • emergency landing
Q2

How did the tarantulas get onto the plane in the cargo?

The tarantulas were hiding inside sacks of coffee beans that were loaded into the plane's cargo hold in Ecuador. The spiders were concealed among the beans and remained undetected during loading and pre-flight checks. The pilots had bribed officials to fly the coffee cargo and secretly smuggled three passengers aboard, so they had no reason to inspect the beans closely.

Foreshadowing: The opening scene establishes the corrupt nature of the pilots who were willing to smuggle people for money, implying they would not question the cargo they were paid to transport.

  • tarantulas plane
  • coffee beans
  • cargo hold
  • smuggling spiders
Q3

Why did the mayor want to hide the spider infestation from the public?

Mayor Douglas feared that news of a spider infestation would destroy Finleyville's orange industry, which was the town's primary source of income. He believed that if people learned dangerous tarantulas were in the area, no one would buy oranges from Finleyville, so he initially suppressed information about the threat to protect the local economy.

Foreshadowing: The town's identity as an orange-growing community is established early, making the economic stakes clear when the spiders threaten the orange processing plant.

  • mayor hide truth
  • spider infestation economy
  • orange town
  • finleyville crisis
Q4

What happened to the three illegal immigrants smuggled aboard the plane?

The three hidden passengers became trapped in the cargo hold when the tarantulas escaped during the thunderstorm. They were forced to fight the spiders with shoes and improvised weapons in the cramped darkness, but were ultimately overpowered by the relentless arachnids and did not survive.

Foreshadowing: The pilots' decision to smuggle passengers as payment for their scheme directly leads to these innocent people being trapped with deadly cargo with no way to escape.

  • smuggled passengers
  • cargo hold
  • illegal immigrants
  • spider attack
Q5

How did the wasp sound trick work against the tarantulas?

The town discovered that the sound of buzzing wasps disorients and immobilizes tarantulas. When exposed to this sound, the spiders become confused and stop moving, allowing people to capture them in buckets of alcohol which kills them. This method was crucial for clearing the spiders from the orange packaging plant and surrounding areas.

Foreshadowing: The timeline mentions early on that the spiders are banana spiders, known for their aggressive nature, which made direct confrontation dangerous and necessitated a creative solution.

  • wasp sound
  • spider control
  • tarantula weakness
  • alcohol kills spiders
Q6

Why did Cindy's brother die from the spider bite when others survived?

Cindy's brother Matthew was bitten by a tarantula and died despite medical efforts. The movie establishes that the banana spiders are highly venomous and among the most dangerous in the world. While some victims survived with treatment, the severity of the bite and individual reactions varied, and Matthew's was fatal.

Foreshadowing: Earlier, a bitten bystander collapses but breaks into vaudeville songs, suggesting varied reactions to bites, though not all survive.

  • matthew death
  • spider bite fatal
  • banana spider venom
  • cindy brother
Q7

What were the strange symptoms victims showed after being bitten?

Dr. Hodgins struggled to diagnose the victims, who displayed baffling symptoms that confused the medical community. One notable symptom occurred when a bitten bystander suddenly collapsed and began singing old vaudeville songs, a bizarre reaction that puzzled doctors trying to understand the spider's venom effects.

Foreshadowing: The venom's unusual effects are hinted at when the spiders are identified as banana spiders, known for potent venom.

  • spider bite symptoms
  • vaudeville songs
  • venom effects
  • medical mystery
Q8

Why did the spiders infest the orange processing plant specifically?

After the crash, tarantulas spilled from the wreckage and moved toward the nearby orange grove and processing plant. The spiders were attracted to the warm, industrial environment and spread throughout the facility. The plant became the central battleground because it was where the town's economic livelihood was concentrated, making it both a strategic and symbolic target.

Foreshadowing: The crash site being near the orange grove establishes the proximity that allowed the spiders to spread to the plant.

  • orange plant infestation
  • spider spread
  • finleyville factory
  • agricultural threat
Q9

How did the plane crash in Finleyville lead to a town-wide spider infestation?

When the plane crash-landed near Finleyville, fire broke out at the wreck site, causing the tarantulas to escape from the damaged cargo hold. The spiders then moved from the wreckage toward the adjacent orange grove and eventually into the community and orange processing plant. The spread was rapid because the spiders were already free and the crash distributed them across a populated area.

Foreshadowing: The timeline shows the crash creating fire at the site, which forced the spiders to flee the wreckage and seek shelter elsewhere.

  • spider infestation spread
  • plane crash consequences
  • finleyville outbreak
  • orange grove spiders
Q10

Why were the banana spiders considered so dangerous?

The Beck family and local experts identified the spiders as banana spiders, describing them as the most aggressive and venomous spider in the world. Their combination of highly toxic venom and aggressive behavior made them particularly deadly, causing multiple deaths and requiring extreme caution when dealing with them.

Foreshadowing: The movie establishes early that these are not ordinary spiders but a particularly lethal species.

  • banana spider danger
  • aggressive spider
  • venomous tarantula
  • world deadly spider
