The cancer cell, a tiny pinpoint of life, is the target against which scientific research is levelled. Cures have been found for a succession of once invincible diseases, but cancer still presents an enigma. The film traces, by means of greatly magnified sequences, the growth and multiplication of a single fertilized cell into an adult man, and asks why, after the body has reached maturity, some outlaw cells begin a persistent and subversive growth of their own. The answer may come from any part of the world, as scientists are seen in many centres painstakingly following every clue that may lead to an eventual solution.
