The premise of *Sirens* is a rich foundation for a dark comedy, focusing on the stark contrast between two worlds. The story is set over a single, pivotal weekend when Devon DeWitt, played by the Emmy-nominated Meghann Fahy, arrives at the exclusive Cliff House resort where her estranged sister, Simone DeWitt, played by Milly Alcock, is employed. Devon's intention is to seek Simone's help in caring for their sick father, Bruce DeWitt, a request that immediately throws the sisters' already strained relationship into turmoil.

The series, created by Molly Smith Metzler, who also developed the acclaimed series *Maid*, is expected to explore themes of wealth, class division, and the complicated bonds of family with a biting, satirical edge.

The characters played by the A-list supporting cast further complicate the sisters' weekend. Julianne Moore’s character, Michaela "Kiki" Kell, and Kevin Bacon’s Peter Kell are part of the elite world that Simone now inhabits, a world that is a complete departure from the sisters' shared working-class roots. Glenn Howerton, known for his masterful portrayal of the high-functioning sociopath Dennis Reynolds, is sure to deliver a nuanced and darkly comedic performance as Ethan Corbin III, adding another layer of tension to the Cliff House environment.
