Netflix's Sirens is a dark comedy with an exceptional cast. The series follows Devin DeWitt as she heads to her sister's place of employment—a millionaire's mansion—in hopes of dragging her sister Simone back to help care for their father with dementia. The only problem is that Simone's boss, Michaela, seems to have some strange influence over the people around her, especially Simone. Sirens is dark and mysterious, but these details are juxtaposed by the unique brand of comedy that drives the series forward. Naturally, this requires a talented cast of actors to make work.

Sirens, which releases on Netflix on May 22, 2025, comes from creator and executive producer Molly Smith Metzler and is based on her stage play, Elemeno Pea. The dark comedy series features an exciting cast, with actors best known from projects like The White Lotus, House of the Dragon, May December, Beverly Hills Cop: Axel F, and much, much more. The characters these performers play are full of their own dark secrets, which are slowly revealed as they are pushed and pulled to their breaking points. Sirens is pure intrigue and mystery, and understanding its characters is the perfect place to start.
