The famous Liberty Train mysteriously disappears and Black Canary calls a meeting of the JSA. But they have disappeared because they are the prisoners of the New Injustice Society. The Canary finds the Harlequin at JSA HQ and, before they know it, the Icicle freezes them both and takes them to the gang’s HQ. Harlequin uses her special glasses to hypnotise the JSA back to their old selves, and when they return to their senses, they discover that the Injustice Society plans to steal four of America’s greatest treasures. The JSA vows to stop them from doing so.
