Ethan still doesn't know what happened to his missing brother four months ago. No idea where he went, who took him, or where to find the answers. But then he discovers Fizz, a mutant who's acid spit can melt off a man's face, and he has a new lead.

Meanwhile, Carlo Martelli is in a rage. His cousin's murder can only be a threat to his rule in the local mafia. The immediate suspect is the traitorous Michael Bello who ratted him out to the police. As the mob war erupts, Fuse finds himself in the cross-hairs, which may have been a trap for him all along.
