The clues reveal that the thief is pretty stewardess Miss Braslow, who dropped the jewels by parachute to her hideout in Devil's Junction. Sandy finds Chuck immobilized by the Gravity Ray--with a tiger about to attack him. After he's free by using POPS' force field, they realize that Sue is missing. She has been captured and taken to Dr. Strange's cave, where she is fighting a battle of will with the Mind Interrogator. A robbery that mysteriously parallels the plot of a play in which Alistair James is starring takes place during his yacht party. Closely following the script, the Teen Angels track down the real culprit, Wilton Weeks, the understudy, who wanted to frame Jones to get the starring role for himself.
