Marty and Speed are middle-aged San Francisco cabbies who hack to support their fading dream of making it as professional actors. Perpetually down on their luck, the friends find escape and camaraderie among their fellow drivers, playing cards and telling stories of backseat conquests, until one night when a dreaded "Signal 7" (driver's call for help) comes over the wire.

Charley Tate is an old windbag, often a braggart, but somehow always lovable. Married over fifty years to his ever-patient wife Lucy, the two of them are on their Golden Honeymoon in Florida. Everything goes perfectly... until Lucy meets her former fiancee who's also vacationing with his wife. Suddenly there's a comic competition between Charley and the old boyfriend for Lucy's attention. After fifty years, cantankerous Charley has to win his girl all over again!
