In a clandestine laboratory, a crazy scientist was researching a way to force human evolution through a radioactive substance.
The mad scientist kidnapped people he used as guinea pigs in his experiments.
After a few months of investigating the disappearances, the FBI discovered the location of the laboratory and sent men to capture the scientist and free the kidnapped people. Unfortunately, no one from the agent group returned.
Believing that the scientist would be very well prepared, they asked for help from the army, which sent a troop to the laboratory. This time, when they got there, they found that the scientist had abandoned the building and taken everything in it away.
The mad scientist became a fugitive from justice and the FBI continued to investigate with help from the CIA. After 5 years they finally managed to corner the mad scientist by invading the laboratory he was using at the time and freeing the kidnapped people who were there.
In a desperate escape attempt, the mad scientist used a secret passageway that took him to an underground garage, where there was a truck with a load of radioactive material from his research. He thought he got away with it when he hit a highway, but a car with FBI agents passed him and the agents on board recognized him, calling for backup immediately. This began a frantic pursuit.
The crazy scientist went through all the blocks and passed through wherever the truck fit. At one point he started heading for the city and in order not to involve more innocent people, a sniper shot from a helicopter and hit him in the head, killing him instantly. The runaway truck went straight and fell into a canyon, exploding when it hit a rock in the middle of the river below.
With the death of the mad scientist the case was closed and the guinea pigs returned to their homes, returning to normal life. At least, that was what they believed.
The effect of the experiments took some time to appear, bringing about a transformation in the person. Who is the former guinea pig?
