 In Mexico, Thrush operative DeSada covets Project Gamma, a "rocket transport" that can travel 5,000 mph. Scientists who are developing the aircraft are being abducted by DeSada and their knowledge "drained" by a high-tech device. April and Mark dodge death traps as they seek to halt the plot. Among them: a remote-controlled car with April inside headed over a cliff and a roll of wicker wrapped around Mark that has been whetted and is rapidly shrinking around the U.N.C.L.E. agent.
