Sabrina tracks her runaway cat, Salem, who has used his magic ""time ball"" to blast everyone in time back to 1979. Meanwhile, Judy is bemoaning the lack of a man in her life, but when Marty turns the family dog into the loyal and loving ""Bob,"" she gets more than she bark-ained for on the disco dance floor; and Marty tries to create his own magic with Sabrina hoping to win her heart even if it takes a thousand years.
When Marty DePolo dies after eating a six-month-old hamburger, he is chosen to be the guardian angel of his best friend Steve Beauchamp.
Fearing Steve will be rejected when he asks Jessica to go out, Marty pretends to be her when Steve calls. But rather than let him down gently, Marty sets up a date and, in an effort to save his friend from heartache, actually morphs into Jessica, turning a dream date into a nightmare.
