Conrad, who suffers from OCD, dreams of becoming a chef. One day he meets Molly who he finds fascinating. The problem is that suddenly she is a completely different person. And soon again. It turns out she is schizophrenic with multiple personalities. But Conrad doesn't give up but try to deal with her and wanting to help her while loving her, all of her personalities (almost anyway).
The concept may be fun, but it fails a bit on two things. On the one hand, I find it hard to believe that schizophrenia works the way it does in the film, and on the other hand, the film does not have its romantic ending (even if it is hinted at in the last scene).
