Quantum Leap was a television series that revolved around the adventures of Sam Beckett (Scott Bakula) and Al (Dean Stockwell). Sam was a scientist who stepped into the Quantum Leap machine for the purposes of time travel and found himself stuck in time "leaping" around from person to person (sometimes male, sometimes female, sometimes old, sometimes young) through different periods of time (and sometimes different countries). He always tried to change that person's life for the better as they were always at a crisis when he leapt into their bodies. Al appeared to him at times as a hologram and provided him with information about the person's history and other useful information (as was a source of sarcasm).
