Ryszard Malewicz, a young inventor, is out of work. He had been waiting for months for a response from the ministry to which he had sent plans for his invention, an explosive of extraordinary power. Desperate Ryszard is comforted by his mother and his fiancée Maria.
Bielecki (Gregori Chmara) becomes determined to become a famous writer, but the means he employs in achieving his goal are far from ethical. Bielecki discourages his friend Jerzy Gorski (Artur Socha) by telling him his new work is rather poor, driving him into despair. But Bielecki is such a good friend that he even provides Gorski with the morphine so he can overdose too. With Gorski out of the way, Bielecki can now peddle his friend's book as his own. However, it doesn't take long for Bielecki's evil ways to catch up to him.
