Finally released, he tries to piece his life together working as a bartender and reading literary classics to the unruly cockroaches infesting his taxi. On the anniversary of his arrest, Wynston picks up two white Americans just kicked off a cruise ship. The next day, the ship reports a deadly viral outbreak. As the tourist economy collapses, the island succumbs to riots and a devastating spiral of violence, and Wynston's fate becomes entwined with that of three strangers.
