Recently widowed Stewart Robertson agrees to spend New Year's Eve with Gary James, a man he only met a few days before Christmas. There's a lot they don't know about each other, and despite Stewart still reeling after discovering Gary's big secret, he remains undeniably drawn to the American parapsychologist.
Gary is keen to make things work with Stewart, but he doesn't know if the man will be able to accept his unconventional job, let alone his belief in all things paranormal. Gary hopes to show the man that his work is more normal than it might first seem by bringing Stewart and Stewart's daughter, Havana, to a haunted castle in the Scottish Highlands.
Stewart is excited by the prospect of spending more time with Gary. He's also excited to not spend New Year's Eve alone in the house he used to share with his husband.
Accompanied by Eleni, a skeptic who takes an instant dislike to Stewart, and Phoenix, Gary's crazy ex, their ghost-hunting adventure promises to be one hell of a ride. Whether Gary and Stewart are still hanging on at the end of it remains to be seen.
