Coneheads

The National Guard detects an unidentified flying object in American airspace. Fighter jets pursue the unresponsive craft and fire on it, causing it to crash into the Atlantic Ocean near Manhattan. The surviving aliens, Beldar and Prymaat, begin their Earth story aboard the ship.

On Remulak, Highmaster Mintot assigns Beldar to conquer Earth for the planet. The couple survives the crash and prepares to make first contact while planning their long-term goals.

Back on Earth, Beldar becomes an appliance repairman using a human disguise. His boss Otto helps him obtain a false identity from local gangsters, a step meant to aid in blending in and avoiding the INS.

Ambitious INS agent Gorman Seedling and his assistant Eli Turnbull launch attempts to capture the Coneheads but fail to close in. The chase underscores the government's struggle to identify the aliens among ordinary citizens.

Prymaat informs Beldar that she is pregnant, confirming the Coneheads will soon have a child on Earth. The revelation reinforces their need to maintain a convincing disguise while planning a family on a new world.

With no rescue sighted for years, the Coneheads decide to blend in with humans. They relocate to the suburbs to save money and avoid detection while integrating into everyday life.

Their daughter Connie is born, and the family adopts the surname Conehead. They buy a home in Paramus, New Jersey, and Beldar opens a driving school to support their disguise and new life.

Gorman terminates his pursuit after a promotion, but a U.S. Senate inquiry scrutinizes the Conehead case for its costs and demands a formal conclusion. The government weighs the extraterrestrial affair and its implications.

Connie, now a teenager, grows up among Earth norms and longs to fit in with her peers. Her friendship and romance with Ronnie Bradford heighten the tension between her identity as an alien and her human ambitions.

Gorman and Eli track the Coneheads to their home and enter by posing as Jehovah's Witnesses. Prymaat detects their Remulak device beeping and alerts Beldar that a rescue vessel is approaching, prompting him to eject the intruders.

Connie is told a rescue is coming; the INS arrives to arrest the Coneheads. Ronnie helps stall the agents while the rescue vessel arrives, allowing the Coneheads to prepare for departure with the rescue team.

The rescue ship arrives just in time, and Gorman and Eli are taken aboard along with the Coneheads. The group is brought to Remulak for the next stage of their journey.

On Remulak, Mintot welcomes Earthly gifts, including Gorman and Eli as slaves. He notices Beldar's capped teeth and accuses him of treason, forcing him to fight the Garthok. Beldar defeats the monster by using his Earthly golfing skill to dislodge a rock that chokes it, earning Mintot's pardon.

The Highmaster pardons Beldar and allows his return to Earth with Prymaat, Connie, and Gorman. Eli stays behind as Mintot's ally. Back on Earth, Gorman grants the Coneheads green cards, and the family settles into a new life on Earth, prioritizing Connie's happiness.
