Newlywed Oliverio receives disturbing news that his mother is on her deathbed. He travels to a remote part of Mexico to fetch a lawyer who can sort out her will. Leaving his wife behind, he embarks on a bus ride that’s interrupted by an increasingly absurd series of episodes, including an impromptu birthday celebration; a one-legged man writhing in the mud; come-ons from an insatiable small-town belle, Raquel; and Oliverio’s frequent, Freudian nightmares.
