Your blood may run cold, but you now find yourself pinioned to the story.

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's masterful storytelling did its job. The message was clear. No need to overdo.

Close shines in drama with strong language, adult themes.
