An Ice in a Warm Sea (1983)

The old shipyard repairman ust-Nazar returned to work after an illness. They were already preparing to see the old man off to retirement. But Ust-Nazar was able to convince his superiors of his efficiency, and they instructed him to repair the old boat. By spring, the boat was ready for sailing. When a huge ice floe threatened the oil rig during an ice break, the old man, without thinking about his own life, went with a battering ram to the ice block.
