Leavey, played by Kate Mara, is the former U.S. Marine corporal and Iraq War vet who completed more than 100 missions with combat dog Rex before both were injured in a 2006 IED explosion.
Leavey received a Purple Heart and an honorable discharged after her recovery, while Rex was kept on active duty. Leavey spent the next 5 years fighting to adopt the dog even while Rex was scheduled to be euthanized after developing a palsy.
