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.

Cliff transforms his neighbor into a beautiful woman; Rebecca says she'll sleep with Sam if she can't quit smoking.

Sam rushes to buy Rebecca a Christmas present after he discovers everyone else bought her one.

Norm agrees to paint Cliff's apartment, but a fight ensues when Cliff refuses to pay him.

A priceless vase is destroyed when Sam, Woody and Rebecca cater a party at the chairman of the board's mansion.
