The Lucky Ones (2008) on Netflix

After suffering an injury during a routine patrol, hardened sergeant TK Poole is granted a one-month leave to visit his fiancé. But when an unexpected blackout cancels all flights out of New York, TK shares a ride to St.Louis with two similarly stranded servicemen: Cheever, an older family man who longs to return to his wife, and Colee, a naive private who's pinned her hopes on connecting with a dead fellow soldier's family. What begins as a short trip unexpectedly evolves into a longer journey. Forced to grapple with old relationships, broken hopes and a country divided over the war, TK, Cheever and Colee discover that home is not quite what they remembered, and that the unlikely companionship they've found might be what matters the most.
