This was a cool little straight-to-video horror movie from a few years back. It starred Jeffrey Donovan (Burn Notice) and Matthew Fox (Lost). Both are living in a post-apocalyptic future where a zombie plague has been halted by freezing temperatures. Donovan is raising a little girl but she is drawn to Matthew Fox's hermit character who lives nearby but never interacts with them.
The story of their lives is told in flashback as both were in love with the same woman and we keep getting a different idea of whose daughter the little girl is. This is the emotional underpinning of the story that starts getting scary when the zombies find a way to adapt to the cold and continue their rampage. The whole thing is pretty well-written and well-acted considering it probably had a very modest budget. You really feel the weight of the past holding these two former friends down and when they inevitably join forces to protect the girl, you can't help but root for them.
Another not bad little gem hiding out in a Redbox or Netflix queue near you.
