It's based on the Stephen King book. It's about a guy who got put in a coma and when he woke up he found that he could see the future and past. In most episodes he has a vision of something bad happening and he has to find out exactly how and he has to fix it. It has a lot of suspense, and mystery, sort of, that leads up to the suspense.
He saw into the future that some kid was gonna bring a gun to school and go crazy with it, but he figured out it's in the way future. Pretty cool stuff. And someone gets hit in the head with a beer bottle.
