Doktor Gruber
Rita Vogt is a radical West German terrorist who abandons the revolution and settles in East Germany with a new identity provided by the East German secret service. She lives in constant fear of having her cover blown, which unavoidably happens after the German re-unification.
Schäfer
Two people love each other when they know they should not. Their parents' and friends' pleas, their social backgrounds and reputation, their careers; everything is used to make them give each other up. Flattery, lies and threats finally drive Frank to despair and Karin to treason. But it is not due to their parents' hatred, nor to any greed for inherited wealth. Rather, the mere conjecture expressed by the authorities is enough to set off a merciless mechanism.
Peter „Kamminke“ Galetzki
Frank and Kamminke study informatics in Leipzig and have developed a program that enables a computer to automatically find and correct errors in its software. Freshly graduated, they are relocated to a remote Thuringian village after causing a computer breakdown. There, they are supposed to work in a small company that has no clue of economic management. The rather helpful computer system from West Germany plainly lacks compatible software. But Frank and Komminke are not allowed to work with the hardware , although it is them who could make most out of the complex system. Eventually, and with the help of consultant Petra whom both are in love with, they break into the system control room on New Year′s Eve and start up the computer with their special program.
At the beginning of the 50s, two extremely disparate men meet in a private sanatorium for consumptives: an officer in the People's Police, Josef Heiliger; and a young Protestant curate, Hubertus Koschenz. On account of their consumption, they have to share a room. Initially, this is the only thing they have in common.
