Kate Mara ("House of Cards") stars in this schmaltzy (but mostly apolitical) combination of war drama and inspirational animal tale. Picking up where 2015's Max and 2016's Army Dog dropped the bone, this mildly patriotic docudrama (inspired by a true story) follows the titular troubled young woman into the Marines, where she gets stuck cleaning out the K-9 kennels. There, she meets undisciplined German shepherd Rex. Naturally, they form an interspecies bond and are soon deployed to Iraq, where they must learn to love and trust one another. Later, when our vet returns home to the states, she fights to adopt her canine soulmate with help from Sen. Chuck Schumer. (No, really.)116 minutes PG-13.
