Soap opera writer Deborah Peltz can handle any kind of drama, so long as it's not attached to her sister Sharon. A wedding planner in Boca Raton, Sharon thinks she has the answers to everything, but with three divorces under her belt, she should be the last person on the planet to dole out the eye roll-worthy advice she heaps. Normally, Deborah survives her sister by keeping her distance safe in the bustle of New York, but when their mother has a heart attack in Florida, she drops everything to be near her. Burying the hatchet with her sister is a challenge in and of itself, but when they both fall for their mother's handsome cardiologist, winning him over and earning themselves an invite to his place becomes an obsession. But when they find him dead in his waterfront home, neither sister wants to be near the place. Now the prime suspects in his murder case, they must stick together to stay alive. Hiding out in the Bahamas may be their only chance-if they don't kill each other first.
