Premise: 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.
