The movie The Lucky One is based on the Nicholas Sparks book of the same name.
U.S. Marine Sergeant Logan Thibault (Zac Efron) returns from his third tour of duty in Iraq, with the one thing he credits with keeping him alive – a photograph he found of a woman he doesn’t even know. Learning her name is Beth (Taylor Schilling) and where she lives, he shows up at her door, and ends up taking a job at her family-run local kennel. Despite her initial mistrust and the complications in her life, a romance develops between them, giving Logan hope that Beth could be much more than his good luck charm.
