When 18 year old Andie is found whipping her own ass in her grandfather's barn, her friend, Zooey, is as surprised and turned-on as the embarrassed Andie. Zooey takes over, using the birch whips on Andie ass, quickly turning the occasion into one that has them both cumming in the steamy heat of that hot summer night. Though Andie begs Zooey to keep quiet, her irrepressible friend soon spills the nasty secret to Andie's best friend Harper and boyfriend, Billy. Suddenly, the awkward, once painfully shy, farm girl has a Master in charge of her life and two cunning Mistresses on the sidelines, happy to attend the amazing show that Billy makes of her. When she's ordered to surrender, there's nothing this girl won't do for the sexual thrill. The Forrest's barn becomes their den of iniquity, as this despotic trio spends their summer torturing their submissive plaything. She is inventively bound, whipped, brutally fucked, anally used, gang-raped and forced to ride naked in Billy's Jeep whenever they leave the farm. Abusing the girl for sport becomes a summer pastime none of them are likely to forget. Yet, when this decadent season finally ends and the wildness abruptly stops, Andie's left with her memories feeling abandoned and lost. Though the summer may be over, this trio Doms is haunted long after by their crude and heartless treatment of Andie. When she turns up missing, their guilt brings them back to find her. There are few clues to her whereabouts, the police suspect foul play, her friends fear she has a sexual new master. But the truth about this summer of sadism will shock them all, when they are forced to face the truth about themselves.
