Four living beings, created in laboratories by the H.U.B. company, rebelled and decided to hide in the same secret laboratory in which they were created. Keeping silent about the structure, however, is not easy, the H.U.B, a leading company in the sector of Biological Units, is on their trail and will not stop until it has found them. The group is forced to carry out various tasks, more or less legal, to protect their lair and remain anonymous. They are the DEATH SQUAD.
