 Sam Malone s drinking problem (which led him to buy the bar Cheers) soured his career as a pitcher for the Boston Red Sox. When a young teaching assistant named Diane Chambers is left by her Professor fiancée, she took a job waitressing at Cheers, leading to a rocky, on-again, off-again relationship with Sam. The bar where everybody knows your name is home to: Sam s old Coach, naive farmboy Woody, know-it-all Cliff, bitter waitress Carla, troubled psychiatrist Frasier and his wife, and regular Norm, owner of the hugest bar tab.
