Radiation affects the Manhawks giving them superior strength to escape their imprisonment. They then steal the entire plant Thanagar while Shayera is there visiting her parents. Haekman traces the radiation the the planet Rann, where Sardath has counteracted the Zeta Beam radiation and the radiation with which Kanjar Ro infected him that would kill him if he stayed on Rann more than a year, but the treatment as it stands will kill him if he returns to Earth. Adam and Alanna's wedding is interrupted by an attack on Rann from the Manhawks, who have identified it as the source of the radiation that enhanced their strength, which has begun to fade.
Adam and Hawkman team-up to defeat the Manhawks, leaving Hawkman free to determine what happened to Thanagar (next issue!)
