January 17th 1958: The cold war is raging on the Earth. On Mars, the war is not so cold. The NATO and the Soviet Union confront each other to gain control of the Red Planet.
One of the two Americans rescued by the team is named Davidson. He recovers in a few hours and gets permission to search building a11, supposedly a crematorium. He remember seeing something very strange there: a human shaped blue light. Then he remembers nothing. The team lead by Ratti escorts Davidson in this exploration.
As soon as the soldiers enter the building, they are confronted by two Russians. One immediately runs to the right, where a pit and a ladder apparently take to an underground floor. The other Russian shots and hits Ratti.
Campano and Verdi fail to stop the Russian directed to the ladder. The other one keeps fighting. Davidson hits the running Russian, but he still manages to disappear down the ladder. Campano and Ratti finally defeat the other one in a furious brawl. They found in his jacket a map of a Crater that the NATO forces call “Rogers”.
The team goes down the ladder, but they are immediately confronted by heavy fire. Ratti and Davidson are knocked down and the team must retreat.
