In a staid English seaside town after the Second World War, young Lynda grows up with her widowed father and younger sister. Rebellious Lynda has been swearing constantly from an early age. At sixteen, she becomes more exhibitionist and seeks out sexual encounters challenging the prevailing lower-middle class attitudes to sex. She eventually becomes pregnant by an acquaintance of her father.
The Doctor, Tegan and Turlough arrive in Little Hodcombe, where the townspeople's re-enactments of English Civil War battles are causing a dormant entity, the Malus, to re-awaken.
