When four couples receive invitations to try out a luxury island resort, they are excited for a week of relaxation and reconnecting.

For some, it's the honeymoon they never had the chance to take.

For others, it's a last-ditch attempt to save their crumbling marriage.

But when one of the group members ends up dead on the night of a terrible storm, what was once a paradise soon becomes a prison.

Trapped on the island with no cell phone service and no means of escape, the couples fear the worst.

What exactly happened to their friend?

And could they be next?

Determined to learn the truth, the couples search for answers, but only discover more secrets. Friendships, loyalties, and marriages are put to the ultimate test as they grapple to decide whom to trust and who could be a threat.

Will they make it off the island?

Or will the perfect getaway turn into their last?
