car carrying two Ministry officials, enroute to investigate the budget overruns on Professor Rushton's latest project, vanishes under escort. Steed goes to investigate, and discovers the hard way where the money has gone; to build a device capable of shrinking anything to a fraction of its normal size. While Rushton has great science- and industry-oriented plans for the device, his assistant Chivers has plans of his own... to make a profit, and dispose of anyone in his way. Steed, inches tall, manages to telephone Emma with a warning, but she is captured by a co-conspirator of Chivers, and next faces the shrinking machine. How will Steed and Emma get through this one?
