Fiona is delighted when her new mother-in-law, Rita Landry invites her and Nathan to a private island in the Bahamas owned by a US ambassador. Sun, sandy beaches, and romantic tangerine sunsets await the newlyweds, but for Rita and her executive assistant, Hal Underwood the trip to Deep Blue Isle is a working vacation. Ambassador Taslow has summoned them to the island to discuss a scandal he has fallen victim to. However, when the Landry’s and Hal arrive, they find less than welcoming circumstances: no internet or Wi-Fi, mischievous monkeys, a dangerous tenant, and then there’s that pesky dead body.
A storm is brewing on Deep Blue Isle, and it has nothing to do with wind and rain.
