Everything ought to be perfect in the magical Long Island town of North Hampton now that Freya Beauchamp's twin brother, Freddie, is back. But their mother, Joanna, has always favoured son Freddie, and his assertion-that Freya's fiance Killian Gardiner (Baldur) was the one who set up his downfall-threatens to fracture the delicate family dynamics as the Beauchamps are forced to take sides against each other. Freddie spends his days either on the couch sleeping, or sleeping around. When their father Norman helps him find a job on a fishing vessel, Freddie's uncontrollable magic causes mayhem aboard the ship and lands him in even more hot water. Level-headed sister Ingrid attempts to maintain the peace between the warring twins, but she has problems of her own: her human boyfriend, detective Matt Noble, becomes entangled in a complicated investigation, and when the magical creatures at the heart of it come to Ingrid for help, she has to choose between helping her kind and staying loyal to her love. Freya and Killian plan their wedding only to discover an ancient rivalry that could keep them apart for ever. Things come to a head when the culprit behind Freddie's imprisonment is finally revealed, but it may be too late to staunch the poison that's been released in the family and the town.
