Sanctuary

Evan "Buck" Buckley moves to LA, determined to make a new life for himself. He takes a job as a firefighter and keeps a low profile, but he is soon won over by the warmth and caring of the close-knit fire family, especially that of widower Eddie Diaz. With the help of Eddie and his kid, Buck learns to love and trust again -- but when a mysterious stranger arrives and starts asking questions, Buck's dark past threatens to reclaim him.

Note: While this is based off Nicolas Sparks' Safe Haven, I just want to make clear that this is based off the movie, not the book.
