The Earth seemed to be coming to an end. Robin, while protecting Nocturna, was attacked by Night-Slayer. Batman got Robin's message while visiting the hospitalized Catwoman; he left to join his partner. Selina broke out of the hospital. Night-Slayer stabbed Nocturna three times while telling her he loved her. Batman arrived and took him on. Robin tried to get Nocturna (who was calling him her son) to safety. Catwoman crashed a helicopter into the observatory where the action was taking place. She helped Batman out, but both her and Night-Slayer were lost in an earthquake. Batman, Robin, Catwoman, and Night-Slayer washed up on the beach. The Crisis loomed near.
