Stef and Lena hesitate to give their blessing when Mariana’s biological grandfather tells her she must be baptized in order to be her new half-sister Isabella’s godmother. Callie’s actions at her birthday party are called out by Stef, and they make a big decision in order to avoid jeopardizing her adoption.

The family heads to Idyllwild for Brandon’s music competition where long-held feelings are revealed and life-changing secrets are unveiled.

Callie is now officially adopted into the Adams Foster family and must put aside any romantic feelings for Brandon. She does so by throwing herself into her “Fost and Found” website, even drawing the interest of an investor.

Callie is surprised to find that Jude is spending time with Jack, a quirky foster teen they met at a foster youth event. Brandon and Mat decide to write a Romeo & Juliet rock musical as their senior thesis project, but they disagree over who should play Juliet. Meanwhile, Jesus asks Ana about the identity of his and Mariana's birth father.

After Callie and Jude discover Jack is being abused by other boys in his group foster home, they turn to foster care advocate Justina to get him help. Jesus attempts to get to know Gabe at work even as Nick urges him to tell Gabe the truth about who he is. Meanwhile, Mariana is surprised when Nick asks her out.

While Stef recovers from surgery, she and Lena grow concerned when they find out Justina wants Callie to support a legislation that they know nothing about.
