All 22 episodes from the fourth season of the award-winning time-travel series. Scientist Sam Beckett (Scott Bakula) gets trapped inside his own 'Quantum Leap' experiment, and leaps into the bodies of people whose problems only he can solve. Joined by the hologram projection of his wise-cracking adviser Al (Dean Stockwell), Sam has to help each person he leaps into before he can leave, all the while hoping that the next leap will get him home. In this series, Sam leaps into the body of a KKK member as he tries to help a black civil rights activist, and also into the body of a chimp trying to survive a NASA scientist's neurological experiments. In the final episode of the season, Sam leaps into Al's body in 1957 in order to prevent the death of Al's married lover. But when Sam makes a mess of things, Al could be facing the death penalty for murder.
