When an off-course Russian space capsule crashlands in the sea nearby, Tibor is the first to reach it. He makes contact with the still-alive cosmonaut inside, who can hear him talking but cannot respond except by knocking on the hull. Tibor, who escaped from Hungary during the 1956 uprising and whose brother was killed by invading Russians, takes revenge by delaying the salvage attempts until the capsule's air has run out and the cosmonaut is dead.
