After waiting far too long in the shadows, pretending to overlook the ineptitude of his master, Dr. Z, Seth finally begins to enact his plan to take over The Alpha Gang.  One of his first successes, he hopes, will be capturing an Ampelosaurus, which has appeared in Moscow, Russia. The D-Team also rushes to the scene and discovers the dinosaur in a railcar on the Trans-Siberian Railroad.  They struggle to extricate it from the train without injuring its countless passengers, even as The Alpha Gang descends to capture the dinosaur themselves.
