Synopsis by Hal Erickson
On the brink of death, terminally ill scientist Jacob Valerian (John Gilbert) transfers all his memories and experiences into the brain of Karl Durand (Howie Mandel), a mentally challenged adult. This sudden influx of knowledge and wisdom has a startling effect on the previously simple and childlike Karl. In fact, "startling" may be too mild a word; perhaps "horrifying" would be more appropriate, especially when Karl begins to use Valerian's technology to capture the minds of others -- leaving their dead bodies behind. "Second Thoughts" first aired on January 19, 1997.
