Catherine has entered a particularly dark period in her life: her father, a famous artist whose affairs she managed, has recently died, and on the heels of his death she's dumped by her boyfriend James. Looking to recuperate, Catherine heads out to her best friend Virginia's lake house for some much needed relaxation. However, once Catherine arrives relaxation proves impossible to find, as she is overcome with memories of time spent at the same house with James the year before. As Catherine reaches out to Virginia with attempts at connection, Virginia begins spending increasing amounts of time with a local love interest, Rich, and fissures in the relationship between the two women begin to appear, sending Catherine into a downward spiral of delusion and madness.
