Pickpocketing is not honest, but it is lucrative. That is, until 17-year-old Charles Main gets caught, and the judge gives the vagrant a choice: Go to prison or join the Army.

Deployed together in the fight against ISIS, their platoon quickly gains a reputation of mythological proportions. Everything changes, though, when Charles witnesses one of his leaders make a fatal mistake on an otherwise impeccable mission. Caught trying to contain the messy aftermath, he finds that being honest and telling the truth aren’t always the same thing.
