Erica has returned to Otter Lake, New Hampshire, to rekindle her romance with Sheriff Grady Forrester at her mom's island retreat, currently closed for the off season. Just ahead of a rapidly advancing storm front, Erica arrives to discover Mom has rented the lodge to a reality TV show. They're filming the wealthy but awful Boatright brood, who've been summoned here by their patriarch because-so he says-one of them wants to kill him. Great television, terrible timing. Not only are Erica's romantic hopes snuffed out like a candle flame, the nasty Nor'easter just became a superstorm... and no one is getting off the island 'til it blows over. When the power fails, it's lights out for the patriarch. Now, marooned with a murdered millionaire and his feuding family, it's up to Erica to take the killer by storm and get back to the business of reuniting with Grady--until death do they part!
