Picking up where we left off in season 2, it's graduation day and the Walker family is turning a corner into a seemingly hopeful future that is until Cordell goes missing, and his mysterious captors are trying to break him down physically and mentally. Meanwhile, Captain James, Cassie and the rest of the Rangers have all hands on deck to bring Cordell home safely but Stella has ideas of her own on how she can help.

Time is pushing forward but Cordell is stuck trying to convince everyone, including himself that he has moved on from the hell of captivity. Meanwhile, Stella comes clean to her dad about how she has been feeling and Bonham shares with Liam a way to work through his trauma.
