Sylvie considers herself a team player at her artificial intelligence (AI) company, but when she uncovers her colleagues' illegal activities, pleasing everyone becomes impossible. Torn about what to do, she confides in her personal trainer, who's dismayed not only by the choices she faces but also by her advocacy of AI, a technology he considers dangerous. Despite the barbs the two trade at the gym, they are drawn to each other. If only Sylvie weren't continually summoned to the Miami estate of her mother and stepfather, where illness, death, a disputed will, and the rekindled ashes of an old flame swirl into a disaster that follows Sylvie back to Boston, bringing harm to her and those she cares about.
