The relationship between Ceto—a siren who left her sisters and the ocean behind—and her 15-year-old daughter, Naia, is tested when Sirenland, their seaside burlesque attraction, is threatened by the untimely death of a guest.
Tucked somewhere along the coast, amid harsh limestone cliffs overlooking the sea, is a renowned and intensely popular roadside attraction known as Sirenland. This glorified boardwalk amusement park is where Ceto, Naia, and several other women live and work as mermaids, performing every day in a large tank and along the beach for hordes of onlookers. The difference between Ceto and her staff, however, is that she’s not just donning a sequined mermaid tail for show—she actually is a siren.
