When Monkey saves a pretty widow from the Demon Spirit of Great Snakes, amorous Pigsy falls snout over trotters in love with her, but she only has eyes for the celibate boy priest Tripitaka. The pilgrims move on, but Pigsy stays behind and tries to win the widow's heart; but time and time again, his true pig nature is revealed. When Monkey goes to fetch Pigsy, Tripitaka and eel-phobic Sandy end up in big trouble.
