In Baxter's Beach, Barbados, Lala's grandmother Wilma tells her a cautionary tale of the one-armed sister, and what happens to girls who disobey their mothers and go into the Baxter's Tunnels. Now Lala lives on the beach with her husband, Adan, a petty criminal with endless charisma whose thwarted burglary of one of the beach mansions sets off a chain of events with terrible consequences. -- adapted from jacket
