Love has come to Crystal Cove. Love in the form of an evil woman by the name of APHRODITE. Although she appears beautiful to those under her spell, in reality she is horribly ugly with no real interest in love. What she wants is the destruction of Crystal Cove itself. Mystery Inc. is helpless to stop her, because her love spell has twisted the minds of FRED, DAPHEN, VELMA, and SHAGGY, making them fall madly in love with each other. Only Scooby isn't affected. He's left on his own to solve this mystery. Fortunately he gets some help from an odd ally... the gang's old nemesis PROFESSOR PERICLES. But is Pericles really there to help, or does he have other plans for Scooby Doo?
