Overview:

Ricky is the hottest water-ski instructor around and has just been rehired by his former employer/camp to whip up attendance. Unfortunately, the camp is in serious financial trouble. The owner of a rival, more popular camp wants to buy them out. Therefore they will have to engage in a mean, winner-takes-all competition that will settle the score once and for all.
