This quest for a cure becomes increasingly urgent as his transformation accelerates. As he navigates the complexities of human relationships and corporate greed, Martin's journey leads to a confrontation that could either save or doom him. With time running out, Martin's intelligence and humanity are tested as he faces ethical dilemmas and a dangerous race against his own biology.
