Plot summary
The plot of Sirens takes place over the course of the Labor Day Weekend. Devon DeWitt (Meghann Fahy) arrives at the lavish estate on the island of Port Haven to reunite with her younger sister, Simone (Milly Alcock).
She works as a personal assistant to Michaela Kell (Julianne Moore), a former attorney and philanthropist who is married to the billionaire, Peter Kell (Kevin Bacon).
Devon grows increasingly concerned about Michaela's influence on Simone, which strikes her as inappropriate. To add to her discomfort is the estate's cult-like management, where employees are kept under constant surveillance, made to follow strict rules, and sign NDAs.
Moreover, Devon suspects Michaela of killing Peter's ex-wife, Jocelyn, and sets off to expose her before it's too late.
She informs her younger sister of their father Bruce's (Bill Camp) early-onset dementia. However, Simone refuses to help out due to her troubled childhood, which led her to attempt suicide.
Simone is secretly dating the next-door neighbor, Ethan (Glenn Howerton), who proposes to her in episode 3, but she turns him down at Michaela's insistence.
Devon, who struggles with alcoholism and hypersexuality, gets involved with Morgan, the captain of Ethan's yacht.
Meanwhile, Michaela accuses Peter of cheating on her and asks Simone to investigate, which leads to Peter making a move on her. When she finds out about their kiss, Michaela swiftly fires Simone in anger. In the finale, Peter ends his marriage with Michaela and pursues Simone instead.
Sirens ends with Simone taking over as the mistress of the House on the Cliff, while Devon and Bruce leave the estate.
