All musically gifted race-driver Lucky Jackson wants in Las Vegas is to score enough money for a new car motor so he can win the Grand Prix. When he encounters sexy swimming instructor Rusty, he considers staying around longer. After Lucky loses his winnings in the hotel pool, he's forced to remain in Vegas long enough to win back his dough -- but now he also wants to win the Rusty's heart. Unfortunately, so does his slick racing enemy, Elmo .
