Der Frühling braucht Zeit (1965)

Was it an act of sabotage or willful negligence? The non-party engineer Heinz Solter is suddenly arrested and accused of approving a defective pipeline that caused a half million loss to his company. At first, the case seems clear-cut for the state prosecutor, but when he probes deeper, he discovers that Solter had acted against his better judgment due to the pressure from his career-driven and authoritarian boss.
