In a flashback at the beginning of the episode, we learn how Angor Rot visited the mysterious "Lady Pale" and traded his soul, which is contained in her ring - the Inferna Copula - for his powers.
Jim uses a rare time-stopping Kairosect (taken from Gatto) to save Claire from getting hit by a truck; rescue Blinky, who is turning back into a troll in front of Barbara; steal Strickler's ring; and take back the second Triumbric Stone from Angor Rot. When the Kairosect's time limit runs out, Jim is confronted by a betrayed Angor, who accidentally destroys the ring, dissipating his soul. He attempts to kill Jim, who escapes, and then pursues Stricker.
