Underground Colony

There is a sharp decline in crude oil production figures in MAKIRT, a company in American ownership. Barla, an engineer, is hospitalised after what appears to have been an accident. The ÁVH people are suspicious that the signs might point to an attempted sabotage. An investigation into the case is now launched. Dalton arrives at the American Embassy to speed things up a little bit. Stumpf, a former social democrat, kills Simics, the drill master, by loosening a bolt. Barla turns out to have found huge oil-fields, following the friendly advice of captain Guszev. This is the reason for his attempted murder. The ÁVH officers eventually find out about the background of the case, and the culprits are arrested. MAKIRT does, at long last, become a real national company. (official distributor synopsis)
