I saw this movie at Church Camp about 13 years ago I guess. It might be Christian-based but I'm not sure. Anyways, there is some time travel involved and someone has a locket that in the past has nothing on the back but in the future has like an "in memorial" of some girl who died of Polio or something. This is killing me. When we saw it at ChurchCamp we didn't get to finish it so now I want to see how it ended, haha! I think whoever went back in time somehow changed the past and the girl did not die of Polio after all...
