When an explosion disrupts work on a monorail, Gilmore, Allison, Rachel and Sir Toby investigate the enigmatic company behind the project. But with government interference on one side, and dangerous businessmen on the other, who can they possibly trust?

Old enemies are becoming friends. Old friends are becoming enemies. As they finally discover who they're up against, and with the future of the planet at stake, the Counter-Measures team have to risk everything to survive.
