Welcome to a provocative and thrilling drama about the scandalous lives of a sexy and sassy group of four girlfriends, each on her own path to self-discovery, as they brave the turbulent journey together.

Meet Savi, a successful career woman working toward the next phase in her life - both professional and personal - simultaneously bucking for partner at her law firm while she and her husband, Harry, try to start a family of their own. Savi's free-spirited and capricious baby sister, Josselyn, couldn't be more different - living single, serial dating and partying, and regularly leaning on her big sister along the way. Their common best friend, April, a recent widow and mother of two, is rebuilding her life after tragedy and learning to move forward, with the support and guidance of her closest girlfriends. And friend Karen, a successful therapist with her own practice, reconnects with the girls after her involvement in a complicated relationship with a patient goes far too deep.

"Mistresses" is a salacious new drama about a group of friends caught in storms of excitement and self-discovery, secrecy and betrayal, and bound by the complex relationships they've created.
