The death of King Henry VIII throws his kingdom into chaos because of succession disputes. His weak son King Edward VI is on his deathbed. Anxious to keep England true to the Reformation, a scheming minister John Dudley marries off his son, Guilford, to Lady Jane Grey, whom he places on the throne after Edward dies. At first hostile to each other, Guilford and Jane fall in love. But they cannot withstand the course of power which will lead to their ultimate downfall.
