I watched this this last week and it was one of the better efforts by the SciFi channel. The premise is that a physics professor finds a brief case that contains the police file of his murder five days in the future. The case has apparently been sent from years in the future.
It is five hours long so there is a lot of other things going on. I would think that you need about five hours to tell a novel length story. As with most TV shows or movies it holds together until the end when they feel that they need to twist the plot so that no one can guess it before hand. Of course logic and/or believebility suffers greatly in these twists. I think it is still playing so I won't say more. Maybe next week I add some spoilers.
