A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

The film may be flawed, but its message is not.

Actress is magnificent and exudes a hypnotic screen presence in this affecting drama.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
