Alternate History

Philadelphia Experiment 2 (1993)

A time-traveling sailor David Herdeg’s (Brad Johnson) participation in a failed 1943 experiment in radar invisibility has propelled him 40 years into the future. An aberration in his genetic makeup enabled him to pass through the portal of time. It has also made him sensitive to any alteration to the time continuum. Another disasterous experiment in 1993 sends a stealth aircraft through the time portal, into 1943 Germany. Simultaneously, Herdeg is pulled into the portal, and finds himself in the terrifying 1993 that resulted from a Nazi victory in World War II.

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.
