The true natures of love, commitment, and reality are called into question in this offbeat drama. One night in bed, Tomas, a magician, begins telling a story to his wife Desirè about Emma and Sal, a married couple whose love life has gone stale. In order to fire up their relationship, Emma and Sal begin playing an increasingly elaborate series of role-playing games, in which they assume different personas -- Sal saves Emma as she is tied to railroad tracks, or Emma must seduce another man to pull her husband out of debt. But the question soon arises -- are Emma and Sal real? And who really holds the power in their lives? Chimera also features Franco Nero as one of the participants in Emma and Sal's sexual fantasies.
