Adventurous couple Jessie and Neal Fox discover not everyone is who they seem to be once the body of a fellow cruiser is found murdered onboard his own sailboat. Old friends Gail and Randy Benton; stunning Catrina Williamson; slovenly, crass, egotist Colin Cox; and willful, young Rena Stine, sailing the sea on her own combine with the remote, tropical coast of Costa Rica to challenge the Foxes’ idyllic lifestyle and test their friendships within the cruising community. This mix makes every day different and unpredictable, but no one expects the community’s climate to provoke murder.
