The evil Dr Gangreen has created an army of mutant killer tomatoes to help him take over the world. During the mutation process he throws out one that`s too big and slow, but it mixes with another experiment, and is transformed into a pretty girl! She escapes with one of the tomatoes, is chased, and gets rescued by a pizza-delivery boy. Together, they must try to thwart Gangreen`s plots and rescue his tomatoes when possible, aided by Tara`s mutant vegetable powers.
