Hippopotamus

A woman wakes to a nightmare scenario; she's hurt, kidnapped, and locked in a room, alone, and she has no memory. The man who has her walks in and announces that he will not let her go until she falls in love with him. She doesn't know what to think. How could she? As days go on she starts to piece things together a bit. Much of the storyline is absurd but just as much of it is absorbing. The cast is about as spare as they come, with only a handful of actors, but the two stars are spot-on.
