Laid-back Sam Malone, a former relief pitcher for the Boston Red Sox, owns and runs Cheers, a cozy bar in Boston. He hires smart, uptight -- and jilted -- Diane Chambers as a server, out of sympathy, but their attraction causes constant bickering. Wacky characters fill the bar: sarcastic waitress Carla, beer-loving accountant Norm, know-it-all postman Cliff. When Diane leaves Boston much later, Sam sells the bar, buys a boat and sails the world, but his boat sinks, so he returns. New, ambitious manager Rebecca Howe hires him back, but they love to hate each other too.

During a Halloween party at Cheers, Cliff meets the girl of his dreams.

Diane fears she is being followed by a deranged actor that is out to kill her.

Sam panics when a series of coincidental events makes him feel old.

Carla and Nick are reunited, briefly, to compete in a dance contest.
