Along the way, Briggs and Lulu drive each other completely crazy, break a handful of laws, narrowly evade death, and learn to let down their guards to have a fighting chance of finding happiness.
If he thought about it, Briggs (Channing Tatum) might believe that the injuries from his service as an Army Ranger have taken everything he had and everything he needed. But he does not think about it.
Despite his doctor’s warnings that he has some permanent impairment, he’s determined to get back into the Rangers. Service gives him structure, purpose, fellowship, and enough adrenaline to not have to think about the many things he doesn’t want to think about, including how much more there is still to lose.
Briggs needs sign-off from an officer to be readmitted to the Rangers, who call themselves “the Army’s premier direct-action raid force.” He has been repeatedly turned down. Finally, an officer says he will authorize Briggs’ reinstatement if he will perform one task, delivering an Army dog to the funeral of a veteran who served with Briggs.
The dog is Lulu, a sweet-faced Belgian Malinois who performed many brave rescue operations, but who now is so severely traumatized from being in a war zone that no one can go near her. She has sent three people to the emergency room and been deemed un-salvageable. Until the funeral, she is muzzled and on Prozac. After the funeral, she is scheduled to be put down.
