In 'Tigerman', Lester Ferris finds himself on Mancreu, an island on the brink of destruction due to toxic pollution. As a British sergeant nearing retirement with a weary heart from life's battles, Lester seeks tranquility in this legal no-man's land. But tranquility is far from what the island offers, as shady enterprises thrive among the toxic clouds. Lester is meant to ignore it all until he befriends a comic book-loving street kid in desperate need of a guardian. As the island's society crumbles into chaos, Lester realizes ignoring isn't an option and is drawn into the role of a protector. Faced with moral dilemmas, Lester's quest raises the question—what kind of a hero does the island and the boy actually need?
