Seeking a fresh start, Megan decides to enlist in the US Marines as an escape from her troubled relationships and small-town life. Her decision marks the beginning of a challenging and transformative journey.

Megan endures the rigors of basic training, where she confronts her limitations and learns the importance of discipline and teamwork. Despite the challenges, she pushes through with determination.

After receiving punishment, Megan is assigned to clean the enclosures of K-9 bomb detection dogs at Camp Pendleton. This is where she encounters Rex, an aggressive German Shepherd who will change her life.

Megan grapples with PTSD from her experiences in Iraq, leading to the end of her romantic relationship with Matt. In her struggle, she also confronts her mother, prompting her to move in with her supportive father.

Motivated by her desire to keep Rex, Megan launches a campaign for military handlers to retire their service dogs alongside her efforts to gather public support through petitions and media appearances.
