In this mediocre film on casino gambling, Stacy (Andra Millian), an innocent young drama student and her teacher Jean (Eve Lilith) head to Reno to have serious fun at "21" by winning, because Stacy has an incredible memory for cards. Once the duo is ensconced at the gaming table, local gambler Will (Kevin Costner) has a sharp eye on Stacy, recognizes her talents, and convinces her to let him take her to his friend and blackjack mastermind, "the Kid" (Ed Semenza) to polish her abilities. His well-laid plans are foiled -- in part -- by the villainous Shecky Poole (Mike Reynolds), who runs a large casino and has his ace blackjack dealer cheat in order to get Stacy out of the game. After some dramatic events, Stacy vows to take revenge against Shecky and starts organizing her mode of attack with several other card players. Unfortunately, under-par acting stacks the cards against this film, but a young, 27-year-old Kevin Costner is the exception, causing critics to notice him in his role as Will.
