A renowned professor of physics named "Dr. Martin Becker" (Ed Nelson) has made a recent discovery that might possibly win him a Nobel Prize. However, a year before that an accident in a laboratory resulted in the death of a colleague which still troubles his conscience. But things begin to change for him as a beautiful woman named "Anne Banning" (Suzanne Pleshette) has come into his life and he falls deeply in love with her. Unfortunately, when she mysteriously disappears all leads point to him as the murderer. And it soon becomes even more complicated than that. At any rate, rather than spoil the mystery of this film for those who haven't seen it, I will just say that there are quite a few twists and turns to be uncovered. Additionally, this film manages to maintain drama and suspense to the very end, which is somewhat unusual for a made-for-television movie. Likewise, I enjoyed the performance of Suzanne Pleshette who is not only attractive but was probably one of the more underrated actresses during this time. Recommended for anybody who enjoys a suspenseful drama of this type.
