It's lobster season at The Shores, a fishing village isolated from The Island in a storm surge. Parker, a collector of antiquities, has moved there with his partner Guillaume, a chef just out of rehab. "Hy" McAllister, a website writer looking for lobster recipes for a client's newsletter, also needs a speaker for her Women's Institute meeting. Enter Camilla, founder of the Lobster Liberation Legion, spouting crustacean right-to-life rhetoric. The legion starts freeing lobsters from their traps, angering the villagers and the man who runs Parker's fisheries empire. In the tragic events that follow, the hidden connection between Parker, Guillaume and Camilla reveals itself.
