When Monkey kills a girl and her elderly parents, Tripitaka is left with no choice but to punish him and send him back home to his mountain of fruit and flowers. No one believes Monkey's story that the people he killed were red, blue and yellow demons disguised as humans. When the pilgrims later discover that Monkey was telling the truth, Tripitaka finds himself in grave danger, and wishes he'd never denied the demons' existence. (thetvdb.com)
