A potentially taut thriller is marred by frequently laughable dialogue in Matthew Montgomery's debut feature.

Perry doesn't even try to successfully integrate the story's comedic and dramatic elements, merely toggling back and forth between them as if in need of mood stabilizers.

There's a scattershot quality to the proceedings, presumably caused by the Canadian writer-director not living long enough to complete the doc. But the individual segments register powerfully and the underwater sequences are beautifully shot, providing ample compensation for the narrative choppiness.

The performances are first rate; besides Woods' solid turn as the emotionally scarred cop, Fukuhara is movingly vulnerable as the frightened Nori and Miyavi takes full advantage of his natural pop star charisma as the long-haired young man who holds the key to the mystery.
