The initial shots of the movie establish Miranda Green (Mischa Barton) as an intelligent young florist with a keen eye for detail, and our period as (approximately - I'm guessing because I don't think they ever state it) the late 1930s. She's invited to the home of an extremely rich industrialist, and even though there's no connection between them and no apparent reason for the invitation, she goes. Where she meets five other equally randomly invited guests. When they arrive at the mansion on a secluded island, they're informed by the staff that their host has been delayed. They're served a meal and given rooms. Given the title, you won't be surprised to find that there's a murder the next day.

The house that most of this takes place in is lovely, but the whole thing is far too structured and mannered. It felt extremely formal from end to end. From the 1930s setting to the dialogue to the old-English-mansion to the "gather the suspects together" cliché. Barton's character Green was too astonishingly observant, too unshaken by the events around her (having never been a detective before). It's attractive, and there was some interest in the mystery, but it was remarkably uninvolving considering there are a couple deaths.
