Spencer Tracy heads a hilariously zany cast that stars Hollywood's greatest comedians (Milton Berle, Sid Caesar, Buddy Hackett, Ethel Merman, Mickey Rooney, Dick Shawn, Phil Silvers, Terry-Thomas and Jonathan Winters) and features cameo appearances by every joker and jester in the business from Don Knotts and Jerry Lewis to THE THREE STOOGES. On a winding desert highway, eight vacation-bound motorists share an experience that alters their plans and their lives! After a mysterious stranger divulges the location of a stolen fortune, they each speed off in a mind-bending, car-bashing race for the loot and the most side-splitting laugh fest in history.
