It's the story of a photographer who one day finds himself reliving his life out of order. Every time he falls asleep, he wakes up on a different day of his life. He finds out he has to save someone before time runs out...and we have plot.
It sounds confusing, but it actually runs pretty straightforwardly, aided by strong writing, and a strong lead in TJ Thyne from Bones. They always take the time to make things clear for everyone watching, and the movie is VERY satisfying.
I've watched a lot of good movies this month. Don't ask me to pick which one I like most.
