Quantum Leap (season 4)

Sam is Frank Bianca (played by Robert Jacobs), a male hair stylist living with his girlfriend, a single mother. When her child witnesses a murder of a mall drugstore clerk just as Sam leaps in, the boy's mother won't let him tell the police what he saw, and the killer is getting closer and closer to make sure that he never will. Joseph Gordon-Levitt also guest stars.

Sam leaps into Katie McBain (played by Cheryl Pollak), a woman who has just been raped by the town's All-American boy. He must make sure that justice is done, resulting in the woman herself being brought into the Imaging Chamber to testify at her trial.

In a very bizarre out-of-the-human host, Sam leaps into Bobo, an astro-chimp whom he must get into the space program – or he'll disappear forever due to unethical helmet testing methods.

Sam leaps into a man named Joseph "Joe" Thurlow (played by Will Schaub) who's dating a much, much older woman and must convince her not to move back to Cleveland with her straight-arrow son and his wife. And somehow he also has to get through a nude version of Hamlet.

As a rash of serial murders take place in San Francisco, Sam leaps into a television reporter named Dylan Powell who must prevent a psychic who is helping the police from becoming the next victim. But when she discovers who Sam really is, they fall for each other and the ordeal becomes very personal.

Sam is a New York City taxicab driver named Max Greenman (played by Ross Partridge) who's trying to earn enough money to get his father his own medallion. Along the way, he meets a woman who claims to be an angel and can see Al, pretending to believe him to be the devil.

Sam leaps into a man named Davey Parker (played by Rafe Battiste) who's part of a trio comedy act, with his male and female partner so in love with each other that they cannot face it. Sam must get the couple to see that they love each other, and prevent one of the comedians from being killed by the Mafia.
