Scientist Garison Fitch discovers holes in time that will destroy time itself if not stopped, and they may be his fault. Two years before, Garison traveled through time and he’s beginning to think his original trip through time may be the source of the holes.

So he must travel through time to a point before he took the first trip to keep himself from taking it. The problem is, he can’t use his time machine to do it.

And time itself may be running out.
