I remember some years back reading a film plot posted here by one of the members. it was about a guy stuck in a jail , and everytime he tried getting out of it he would go into some time warp and return to the beginning? but every iteration , he would get better trained and more equiped to finally break out?

well,, i think i read that plot here , and the storyof the edge of tomorrow sounds a lot like that.

I have read almost everything that is posted on here, but I don't recall anything simular to the plot you discribe.
It is possible that I missed it, but I can't help you.
