The author Peter Ustinov has called his work "Endspurt" a "biographical adventure". Biographical because the somewhat ambitious but later successful writer Sam Kinsale meets here as a twenty-, forty- and sixty-year-old. The interesting thing about this film, however, is that the four Sams are confronted with each other. The diversity of an eighty-year-old life becomes transparent. At the age of 20, Sam Kinsale loves the young Stella and is determined to marry her. But 20 years later, he is fed up with the marriage and wants to leave her.
