Meet the Libner brothers: Marvin, the oldest, is a sergeant in the U.S. Air Force. Buddy, the middle child, is a timid dreamer. Bobby, the youngest, is a handsome rebel in reform school. As kids, they fought a lot and as adults, they barely speak. In the summer of 1963, their tough and eccentric father, Fred, gives them a task: to bring a 1954 Cadillac, bought for their mother, Betty, from Detroit to Miami. As the trip goes on, the three brothers fight and begin to reconnect with each other, while trying to keep the Caddy in mint condition.
