All the episodes from 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.
