Les vacances sont arrivées, mais pas question de se reposer pour Scooby-Doo et ses amis, qui ont une dette à rembourser. Ils vont ainsi travailler chez Thorny, l'oncle de Daphne, qui gère un camp de vacances. Mais en arrivant sur place, ils se rendent compte que le lac voisin cache une étrange créature.
