A police psychologist leaves her position on the force after a hostage negotiation goes south, and ends up an unwitting participant in a time travel experiment.
Pretty good movie, all things considered. I liked how every time she went back in time to fix what went wrong, she ended up making things a LOT worse. Pretty violent film.
I thought Frank Whaley was Matthew Broderick.
Watching "According to Jim," I knew Jim Belushi could act the crazy part, but I was surprised at how well he did with crazy.
Recommend.

Edit: Ever since seeing the Outer Limits (90's) episode "A Stitch in Time," it gave me a whole new way to look at time travel stories. BTW, that is among my top five episodes of the 90's Outer Limits.
