London, 1888. The military joins in the capture of Jack the Ripper and orders the police to remain silent about the operation on pain of death: this is a matter of the highest national importance. The bloody killer turns out to be a scientist who developed a secret formula for the British army, and now the remedy he created has turned him into an almost invulnerable beast and made it possible to escape retribution. Many years later, continuing his experiments, he appears in Mexico and enters into confrontation with the US Armed Forces. This time, superhuman abilities do not save him from death. But this is not the end: the dangerous substance remains and is waiting in the wings. Nowadays, his ruthless power will be awakened by members of the “Event” group, people who are accustomed to doing something completely different - saving lives, and not putting them in danger...
