While Sirens explores themes of power, class and privilege, the show centers around complex relationships between women.

The Netflix series follows Devon (Meghann Fahy) as she travels to a luxurious beach estate to visit her younger sister, Simone (Milly Alcock), after their father gets an upsetting health diagnosis. However, while she's there, she becomes increasingly concerned about Simone's creepy relationship with her billionaire boss, Michaela Kell (Julianne Moore).

"It's a true dark comedy," creator and executive producer Molly Smith Metzler told Tudum. "It's got a Greek mythology vibe." The limited series, which premiered on Netflix on May 22, also stars Kevin Bacon, Glenn Howerton, Bill Camp and Josh Segarra.

While the series explores complicated, even toxic social dynamics between the characters, many of the cast members are happily in relationships off-screen. Moore has been married to her husband, director Bart Freundlich, since 2003. Bacon, meanwhile, married his wife, actress Kyra Sedgwick, 15 years earlier in 1988.
