From executive producer Jennifer Lopez, "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.
Stef and Lena try to maintain calm when their parents descend on the Foster house for a very special celebration. Lena’s dad, Stewart, has agreed to officiate the ceremony while her mother Dana and Stef’s colorful, talkative mom Sharon, attempt to keep things civil while disagreeing on floral arrangements. Sharon tries to strong-arm Frank into attending. Stef avoids telling Lena she plans to return to work as soon as she is cleared. Meanwhile, when Callie’s case against Liam boils down to her word against his, she must decide whether or not to lie in order to get some justice out of the situation. Callie and Jude get some news they've been hoping for, but Callie makes an emotional slip that could destroy any chance they finally have at happiness.
While Lena tries to process the extent of Mariana and Jesus’ lies, Stef and Mike head to Ana’s to try and find Jesus. What they encounter lands someone in the hospital and changes the Foster family forever. While the family waits anxiously for news, tensions rise over the secrets the kids kept from Stef and Lena and even Brandon realizes he’s to blame for covering for the twins. Callie has a heart-to-heart with Brandon to help him understand the perspective of a foster child and Brandon learns how Callie’s mother died. Wyatt calls Callie on her growing bond with Brandon but Callie is all too familiar with the damage that could result from this kind of relationship.
A visit from Lena's beautiful and sophisticated ex-girlfriend reveals a secret yearning Lena has hidden from Stef for the past ten years. Meanwhile, Brandon struggles to please his demanding new piano teacher and rebuffs an offer from Talya to reconnect. When an embarrassing video of Talya circulates around the school, Callie lends her support and urges Brandon cut her some slack. Mike's drinking and Stef's mounting concern do not go unnoticed at the precinct. Mariana and Jesus go to tell Ana to leave Mariana alone. The encounter with his birth mom and her desperate situation drive Jesus to take matters into his own hands, a move that could have dire consequences for the whole family.
Feeling betrayed and angry, Jesus and Mariana get into a major fight. When Lexi’s parents take measures to keep her away from Jesus, Lexi makes a desperate decision, which could have serious and lasting consequences for her and her family. Meanwhile, Lena urges Callie to participate during her weekly group therapy sessions. Callie is conflicted but she opens up to Brandon, who supports her as she confronts a painful memory from her past. Jude hopes to impress his new friend Connor, who comes over to work on a school project.
The Fosters invite Ernesto and Sofia Rivera to dinner, and Stef worries that they will subjugate Jesus to views that disapprove of his non-traditional family. To make matters worse, Stef's conservative father, Frank, shows up and the family dinner threatens to turn into an all-out moral debate. Meanwhile, Callie attends a group therapy session for foster children and meets someone with a connection to her past - a past that will come back to haunt her. Wyatt holds a destructive party at his childhood home, which is under foreclosure, and Callie realizes he's much more hurt than he lets on. Mike shows up late to take Brandon to an important audition with a renowned piano teacher.
