There is a new problem in the solar system. A mysterious organization led by the Lord of Life begins trading in a new drug, “Water of Life.” He gives youth to older people, but only for a while, after which Old Age returns or even comes along with Death. Those who have already tried the drug want to prolong their fleeting youth and are ready to do anything for a new dose. Captain Future and his associates must do what the police cannot - stop the supply of the drug and destroy its source.
