When Shelly's husband Ed goes missing, Sarah, Josh and Ali set out to find him, and instead find themselves lost in their past. Ali can no longer keep Maura's secret from Josh, which sends him into a tailspin. When Maura runs into a Pfefferman family friend she takes a stand for her new identity.

Maura makes a new friend and has a rude awakening at the music festival; Sarah experiences liberation from an unlikely source; Ali makes an unexpected journey to the past.

Josh arrives in Overland Park and delivers difficult news to Colton. Sarah oversteps her boundaries with Raquel, putting the Hineni Seder in danger. A tough conversation with Bryna brings up some big issues between Maura and Vicki.

Ali is blindsided when Leslie goes public with the details of their relationship. Sarah is ignited by a new connection with her daughter's former teacher, Lila. Josh unexpectedly encounters an ex. Shelly takes up improv. Ali joins Maura on her trip to Israel and their journey gets off to a bumpy start.

Sarah and Len divert a family outing to visit Lila's mom, leading to a blowup between the siblings. Ali breaks off from the group to visit her friend Lyfe in Ramallah while the other Pfeffermans engage in some questionably authentic tourism of desert life.
