For the Love of Grace (2008)

Trailer
Most commended firefighter Steve Lockwood misses his accidentally killed wife Molly terribly. Taking risks not by the book, the hero gets suspended. His kid brother Frank Lockwood fails to help him date again. Then Steve saves freelance-author Grace Harding's life 'accidentally', passing her house on fire. She's encouraged to thank him in person, but already engaged with businessman Cliff, who would be perfect if he weren't almost constantly on business trips.
