Synopsis:
Supergirl participates in an interplanetary exchange program with the planet Thetoa. While the Girl of Steel visits the other planet, Euora Doruu, a Thetoan student from Asborg College travels to Stanhope. However, Euora has been kidnapped by the rebellious Disruptor League and replaced with an agent who disguises herself as Linda Danvers. The agent then begins testing a Neuroscon on the Stanhope students.

Supergirl discovers that Euora is still on Thetoa when she is shown a mini-computron which tracks the number of students on the Asborg campus. The Girl of Steel rescues Euora and rounds up the members of the Disruptor League. She has been given a post-hypnotic command not to leave the planet, but using her wits, Supergirl is able to leave the planet. She then returns to Stanhope to apprehend the Disruptor agent.
