A corruption scandal prompted the Demoya family to leave the public eye and head to the seaside town of Rastrenas. For Sarah and her nanny Yarisa, this is a decisive moment. Sarah is eager to break free from the life imposed on her by her family in Santo Domingo. As a passionate free diver, she longs to get close to the sea. There, in the quiet underwater world, she found a shelter. For Yarisa, this move means she needs to return to her hometown, to be with her daughter Mallory, who had to be taken care of by her family 18 years ago. Now, she must face the ghosts of her youth and the stormy relationship with her family and Mallory. Sarah has always wanted to be like Yarisa, to look like her, to be her daughter, which is why she is fascinated by seeing Mallory, a 19-year-old girl who was full of all Yarisa's energy when she was young. In order to please her and alleviate the strange moments in Yarisa's life, Sarah invited Mallory to a party.
