Imbecilic best friends Lloyd Christmas (Jim Carrey) and Harry Dunne (Jeff Daniels) stumble across a suitcase full of money left behind in Harry’s car by Mary Swanson (Lauren Holly), who was on her way to the airport. The pair decide to go to Aspen, Colo., to return the money, unaware that it is connected to a kidnapping. As Harry and Lloyd who have fallen in love with Mary are pursued across the country by hired killers and police, they find both their friendship and their brains tested.
In this zany sequel, time-traveling duo Marty McFly (Michael J. Fox) and Dr. Emmett Brown (Christopher Lloyd) return from saving Marty’s future son from disaster, only to discover their own time transformed. In this nightmarish version of Hill Valley, Marty’s father has been murdered and Biff Tannen, Marty’s nemesis, has profited. After uncovering the secret to Biff’s success — a sports almanac from the future — Marty and the Doc embark on a quest to repair the space-time continuum.
