Watch The Fosters series free. The Fosters is a drama series that centers with a multi-ethnic family mix of foster and biological kids being raised by two moms. Stef Foster (Teri Polo), a dedicated police officer, and her partner Lena Adams (Sherri Saum), a school Vice Principal, have built a close-knit, loving family with Stef's biological son from a previous marriage, Brandon (David Lambert), and their adopted twins, Mariana (Cierra Ramirez) and Jesus (Jake T. Austin). Their lives are disrupted in unexpected ways when Lena meets Callie (Maia Mitchell), a hardened teen with an abusive past who has spent her life in and out of foster homes. Lena and Stef warily welcome Callie into their home thinking it's just for a few weeks, until a more permanent placement can be found.
