Reunion is a 2024 American comedy mystery film directed by Chris Nelson and starring Lil Rel Howery, Billy Magnussen, Jillian Bell, Jamie Chung, Michael Hitchcock, Nina Dobrev, and Chace Crawford.

The film is set during the aftermath of a twenty-year high school reunion, when an obnoxious popular student is murdered and his former classmates are left to figure out who among them is responsible.

The celebration is being hosted at the home of successful hedge fund manager Mathew Danbury, and the attendees include police officer Evan West, his best friend Ray Hammond, journalist Jasmine Park, weirdo Vivian Chase, politician Amanda Tanner, former popular girl Meagan Cooper, and their former teacher, Mr. Theodore Buckley.

During the reunion, Evan and Jasmine start to form a romantic connection, while Ray keeps making advances on an unreceptive Meagan until the pair have a loud argument.

A severe snowstorm forces most of the attendees to leave the party early, but Evan, Ray, Jasmine, Vivian, Amanda, and Mr. Buckley are all too drunk to drive and elect to stay at Mathew's house.

Evan and Ray investigate the scene of the murder, noting the window that was open during the snowstorm and a bullet hole in the wardrobe door.

In trios, they search the house for clues, and Amanda is discovered trying to hide a VHS tape from high school of her and Mathew poisoning another student.

Lisa opened the bedroom window to throw off the group's investigation and wore the mascot costume at the party so people wouldn't realize Mathew was already dead.
