Yummy is an orgy of blood, violence, and fun as a young couple travels to a run-down plastic surgery hospital in Eastern Europe. The young woman wants a breast reduction. Her mother is in for another makeover. Wandering around an abandoned ward, the boyfriend stumbles upon a young woman, gagged and strapped to an operating table. She's the result of an experimental rejuvenation treatment. He frees her, unaware that he's just caused an outbreak of a virus that will turn doctors, patients, and his mother-in-law into bloodthirsty zombies.
