Harmony Grace is a breathtaking 27-year old strawberry blonde with piercing blue eyes. Her slim but curvaceous body attracts the notice of all the local men, and she uses her feminine wiles to sell them savory lunches from her food van, which is parked in an industrial area. As she struggles to keep up with the demand for her fare, she hires Melody Chalmer, a younger woman with sultry brown eyes and dark hair. Melody proves to be a hard worker and quickly becomes popular with their regular customers. But Harmony's urges are not so easily controlled, and she finds herself competing sexually with Melody and others at every turn.
