Out of work actress Ava Beck, reduced to working in a West Village flower shop, starts to watch womanizing hedge funder Peter Greer, who lives near. He likes to romance his girlfriends with flowers. Ava notices bruises on his troubled-looking date named Chloe. Concerned, she follows them after work to Chloe's studio, second floor in the rear of a brownstone. She hears them arguing, climbs up the fire escape just as Greer angrily sees her...and plunges into a world of stunning twists, murder and madness worse than any she could have imagined...
