"Lessons in Time," Part 2 of 2 starring the Atom! Professor Hyatt's miraculous invention, the Time Pool, has gone out of control, and now Ivy University is overrun by dinosaurs, futuristic fighters, and other time anomalies. Professor Ray Palmer, a.k.a. the Atom, must find a way to shut down the Time Pool before the damage is irreparable. But his only shot at success depends not on his size-changing powers, but on his ability as a teacher. And the person he needs most is his slackest student ever!
