Autistic, divorced, and chronically ill Maggie Livingston just wants a 5-star review for her new Bed and Breakfast that will save her family's beautiful Victorian home, but her murdered guests and a plague of unexplained accidents keep getting in the way. It doesn't help that Maggie's guests for a high-stakes week of wedding festivities are her old high-school nemeses and there's a sweltering heat wave gripping their touristy mountain town. Or that she still has feelings for her ex-girlfriend Alice, the local game warden who is currently dating one of the wedding party.

To make matters worse, the morning the wedding guests arrive, Maggie's first guest inconveniently dies upstairs while the hotel inspector conducts his final tour. Maggie and her best friends Mia and Sutton stash the body, but the mystery remains, and chaotic mishaps abound. In the wake of food poisoning, a collapsing dock, rogue alligator, and a swarm of bees flying out of a disco ball at the roller-rink, it will be a miracle if Maggie can keep it together until her big payday at the end of the week, pay her mortgage, and save her guests from a murderer.
