all to Petersen at his island headquarters, staffed by an army of his female robots, including the defective but endearing No. 7 (Vanessa Howard). Drummond and Peregrine are also reunited with Flicky, who has successfully infiltrated Petersen's organisation. Over dinner, Petersen reveals the full details of his plan to use infrasound technology to sabotage the SST1's maiden flight. That night, Drummond sleeps with Helga once more, while Pandora contents herself with seducing Peregrine. In the morning, Drummond attempts to retrieve the infrasound powerboat and is met by Flicky, who tells him she is actually a CIA agent assigned to help him. They are caught by Helga – Drummond escapes but Helga holds Flicky at gunpoint. Petersen sends his robots to search the island for the runaway agent – Drummond is cornered by No. 7, but to his surprise, she deliberately chooses not to reveal his location. Peregrine and Flicky are held hostage in Petersen's control room and are forced to witness the SST1's destruction as he puts his plan into action. Drummond scales the wall of Petersen's hideout, and saves the SST1 from destruction by using Petersen's infrasound waves against him, destroying his control room. Petersen, Pandora and Helga are all apparently killed in the explosion. Drummond, Flicky, Peregrine and No. 7 escape the subsequent mayhem, having retrieved the infrasound device. Flicky reveals herself to be a double agent working for the Russians and escapes on the powerboat with the device. Peregrine, wanting to improve his Russian relations, decides to go with her. As the base finally explodes, Drummond finds comfort in the arms of the beautiful No. 7, who turns out not to be a robot after all.
