The overwhelming screen charisma of Andrea Riseborough is just about strong enough to prevent this identity drama from derailing into art house obscurity.

Good performances and interesting, though undeveloped narrative ideas in this debut feature from writer-director Christina Choe.

Smith-Cameron and Buscemi are both terrific, Buscemi for the fullness of his subtlety (so much going on in the looks and silences) and Smith-Cameron, for the depths of pain she can suggest, even when she plays a surface happiness.

The dueling tensions of the film are quite fascinating.
