Callie convinces Brandon to head out on a mysterious trip that brings them to Mexico. Stef and Lena discover an empty pregnancy test box in the trash and wonder if someone in the house is worried they are pregnant.
"The Fosters" is a compelling drama about a multi-ethnic family mix of foster and biological kids being raised by two moms. Stef Foster, a dedicated police officer, and her partner Lena Foster, a school Vice Principal, have built a close-knit, loving family with Stef's biological son from a previous marriage, Brandon, and their adopted twins, Mariana and Jesus.
Their lives are disrupted in unexpected ways when Lena meets Callie, 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. What happens next will determine if Stef and Lena made the right choice in taking a chance on Callie, and whether they have room in their home - and their hearts - for one more.
