Hercules (Kevin Sorbo) is somewhat startled to learn that his mother, Alcmene (Liddy Holloway), has agreed to marry King Jason (Jeffrey Thomas). Even more startling is Jason's willingness to give up his throne to wed a commoner -- and his choice of successor: Hercules himself, who declines the honor in favor of his mortal half-brother Iphicles (Kevin Smith). Meanwhile, the evil Patronius (Simon Prast), who covets the throne himself, conspires with Hera to sabotage the wedding. The upshot of all this intrigue is the surprise appearance of Perfidia the sea serpent, who puts a damper on the ceremony by swallowing both Hercules and Jason! ~ Hal Erickson, Rovi
