In this wacky comedy, the outrageous, permanently spaced-out duo of Cheech and Chong sells enough of their "specially mixed" ice cream to take the cash and realize their fondest dreams: new guitars, islands in the sun and beautiful women. But, of course, not everything goes as planned. While celebrating their wealth, Cheech meets his long-lost love Donna (Evelyn Guerrero), and promptly escorts her to her posh penthouse. He soon learns, however, that Donna's boyfriend, an ex-con named Animal (Michael Masters), is on his way to her boudoir. Meanwhile, Chong has unwittingly exchanged all their money for a worthless check - and the only way to get it back is to escape into a nearby insane asylum.
