In Yokohama, Japan, Abbey is on a mission to recover a piece of weapons technology from an old friend, Mr. Naoki. As she's about to meet with him, she recieves word that a change of plans has been made and she is also to bring him along. When she lets him know that he is to go with her, his guards enter the room to deal with her threats. Grabbing Naoki, Abbey jumps out the window as the guards open fire. Using a parachute, they safely land on a waiting speed boat driven by Sydney. They ask him for the technology. He says he will be killed when "they" find out it's been taken. Then a sniper shoots and kills Naoki. The bullet hit him in the chest where he had the tech in his jacket pocket.

In Melborne, Australia, the girls are supposed to have a day off when Sydney calls Abbey asking her to go to her location. Fearing the worst, Abbey breaks down the door at a house Sydney is thinking of buying. Abbey fears that Sydney is thinking of quitting Danger Girl because of the sniper. Sydney says she just wants a place to call home when they are not on a mission. As she's about to take the house, both their beepers go off.

The Master Key is apparently a weapong that "every bad guy in the world has always wanted."

In the Arctic Cirlce, a nuclear sub has been accessed by an outside source. The missles have been commanded to self-detonate. The crew abandons ship asthe sub is blown up.
