Having completed his overthrow of Madripoor's underworld, Daken heads to Los Angeles, where he intends to do the same, but he becomes addicted to the city's newest designer drug, Heat, which nullifies his healing factor and gives him a big high. Exhilarated by the danger, he takes risks that bring him to the attention of FBI Agent Donna Kiel when bodies slashed to pieces by claws begin showing up all over the city.
