The Lucky Ones (2008)

Starring Rachel McAdams and Tim Robbins

The story revolves around three soldiers -- Colee, TK and Cheever -- who return from the Iraq War after suffering injuries and learn that life has moved on without them. They end up on an unexpected road trip across the U.S., with Colee on a mission to bring her boyfriend's guitar back to his family because he saved her life, TK seeking confidence to face his wife after a shrapnel injury that threatens his sexual function and middle-aged Cheever planning to hit the casinos in a desperate effort to pay for his son's college tuition.

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 agrees to share a ride to Pittsburgh with two similarly stranded servicemen: Cheever, an older family man who longs to return to his wife in St. Louis, 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.

Well, I almost watched Teaching Mrs. Tingle; but i had to turn because it was so Pathetic--it was a fake attempt of trying to recreate the movie 9 to 5 from the 80's, but very very dumb. So, I ended up watching Barbershop
