Marsha is living a comfortable, quiet life with her dependable boyfriend, David Mitchell (Ted Wass), and building a career alongside her wealthy, respectable father, Tom Burroughs (Efrem Zimbalist Jr.).
Annie’s arrival immediately disrupts the household’s delicate equilibrium, as long-simmering resentment and childhood insecurities between the two sisters quickly bubble to the surface.
Beneath Annie’s carefree, alluring exterior lies a deeply insecure young woman who harbors a desperate need for attention and a history of competing with Marsha.
Sensing tension in Marsha’s relationship, Annie begins a subtle, calculating campaign to seduce David, testing his loyalty and pushing him into an agonizing moral crisis.
As David finds himself increasingly drawn to Annie’s dangerous charm, Marsha remains initially oblivious to her sister’s deceptive game, trusting her family despite growing suspicions.
Meanwhile, their father, Tom, attempts to intervene and keep his daughters grounded, but his presence only fuels Annie’s reckless behavior and deep-seated desire to shatter Marsha’s picturesque world.
As hidden passions erupt and secret betrayals are brought into the light, the trio faces a devastating emotional reckoning that threatens to permanently sever family ties and destroy David’s future with Marsha.
