Widower Dr. Matt Younger and his daughter go to London for a month of dirt-bike racing.

A romance slowly develops between the doctor and Catherine, but there are complications to their happiness.

You Have Struck A Rock! commemorates the special contribution of South African women to the success of the anti-apartheid struggle. It recovers the remarkable "women's campaigns" of the 1950s against the hated pass system. This massive, non-violent civil disobedience movement was only finally crushed by the 1960 Sharpeville Massacre and the banning of anti-apartheid organizations. Lilian Ngoyi, Helen Joseph, Dora Tamana and other leaders recall this struggle and their imprisonment and banning. Yet they remain undaunted, demonstrating the South African proverb: "When you have touched a woman, you have struck a rock."
