Three cosmonauts set off on a flight to Pluto in an inflatable plastic capsule with an ion propulsion engine. The flight lasted one and a half years. The goal of the expedition was to solve Pluto’s last mystery—where did Pluto get its enormous mass? The planet is tens of times heavier than it should be.
During landing, an unforeseen accident occurred: the engine malfunctioned. Fixing it on the spot is impossible, and now the crew is doomed to die.
