From the venom of a Black Mamba, Dr. William F. Paisley, a Nobel Prize-winning scientist, develops a drug that permits tissue, cartilage, and bone regeneration to occur in humans. After losing a hand in a traffic accident, Paisley becomes his own guinea pig and injects himself with the experimental drug. The results exceed his expectations. Great discoveries, however, come with a price. The corrupt CEO of a major pharmaceutical company sanctions theft and murder to acquire Paisley's formula--and the Black Mamba. The world's deadliest snake, the Mamba escapes and terrorizes a Central Texas college town. The drama intensifies as Paisley discovers that his drug produces a bizarre side effect, making it both a curse and a godsend.
