Murder in the Hamptons intersects the worlds of music, money, and murder. A clash between the classes is played out in the Hamptons, when a rapper moves into an elite community with his unruly crew. The residents of Coco Beach, a private enclave tucked away in the Hamptons, are a hoity-toity bunch. Black society snobs with roots in Sag Harbor that run generations deep. So imagine how incensed the locals become when their tranquil summer getaway is infringed upon by TuSmArt, a rapper with money, but without the necessary pedigree to fit into this upper-crust community. When a body is found floating face down at TuSmArt's yacht party, the police waste no time swarming in to find the killer. The snooty locals rejoice, automatically assuming that now the police will rid the area of the unwanted inhabitants. However, their victory song is cut short when one of the most prominent residents of Coco Beach is implicated in the murder.
