Hmm..It’s time for me to write a good article for Criminal Minds season finale episode. As you know, or if not yet, on May 20, 2009, CBS will air its episode with title “To Hell…And Back.” for full episode. Further information, this is as the Season 4 Episode 25. I still don’t know whether CBS will renew Criminal Minds to season 5 or not. Below, you can read the episode’s synopsis and then watch the spoiler / preview.

In among its hardest cases, the BAU is phoned to Detroit to aid hunt down a serial murderer who draws the team into Canada to catch him.
