After Brawn manages to escape, Plas grants her leniency, but she vows to get revenge.; The Phantom Lady rescues Don and an ambassador from a dirigible on which some Nazis had planted a bomb.; Roy, an accomplished chemist in his own right, invents another explosive that scared his co-workers so much that he moved the experiment into his own private lab.
