April Fool's Day

On her 10th birthday, Muffy St. John receives a whimsical jack-in-the-box that surprises her with a tiny alien. This moment encapsulates the laughter and joy of the celebration, surrounded by her friends and family.

A group of college friends eagerly boards a ferry to Muffy's idyllic island cottage for a weekend getaway. Among them are Kit, Rob, and other lively friends, all excited for the adventures that await them.

During a reckless game of 'stretch', Skip is accidentally injured by Arch when a knife is thrown. This incident escalates into chaos as Skip falls overboard, prompting concern from the ferry crew.

The commotion causes Buck, a crewman, to sustain injuries when struck by the ferry while trying to assist. The incident draws the ire of Constable Porter, who scolds the group for their reckless behavior.

Upon arriving at her cottage, Muffy warmly welcomes her friends, showcasing her stylish living and dining areas. The atmosphere buzzes with anticipation and excitement for the weekend ahead.

The group gathers for dinner, though the atmosphere is dampened by Skip's earlier misfortune. Muffy attempts to lighten the mood with playful tricks, but unsettling occurrences soon overshadow the fun.

During the night, Muffy continues to play pranks, including exploding trick cigars and spouting water. These odd incidents, along with eerie newspaper clippings, heighten the sense of impending doom among the friends.

The next day takes a dark turn when the group discovers Skip's body washed ashore. This shocking revelation sends the friends into a state of panic, grappling with the reality of their grim situation.

As tension mounts, Arch finds himself trapped in a snare, while Hal and Nikki stumble upon hidden bodies during their exploration. Muffy's increasingly erratic behavior adds to the group's growing unease.

In fear, the friends attempt to secure the house while they wait for Constable Porter to provide news. Muffy's strange appearance and actions lead to a heated argument with Nan about a secret from the past.

Desperation drives Kit and Rob to unearth disturbing evidence of Muffy’s true nature, leading them to suspect that not everything is as it seems. They begin to connect unsettling dots of the bizarre events transpiring.

In a climactic moment filled with tension, Kit confronts an unseen threat within the house. It becomes shockingly clear that the horrifying events have been part of an elaborate prank concocted by Muffy and her friends.

"April Fools!" Muffy shouts, as the ruse is unveiled and the tension dissipates into laughter among the group. Relief mingles with annoyance as they realize the extent of the elaborate setup.

Later that night, Muffy returns to her room only to be confronted by a jack-in-the-box ominously placed on her bed. Her attempt to crank the handle leads to another startling surprise, leaving her unsettled.

Just when Muffy thinks everything is over, Nan unexpectedly attacks her with a fake knife while laughingly announcing another April Fools' prank. Yet, this final act leaves the audience questioning the true nature of their reality.
