The soldier returns from the front to the three women who love him. His wife Kitty with her cold moonlight beauty & his devoted cousin Jenny wait in their exquisite home on the crest of the Harrow-weald. Margaret Allington his first & long-forgotten love is nearby in the dreary suburb of Wealdstone. But the soldier is shell-shocked & can only remember the Margaret he loved fifteen years before when he was a young man & she an inn-keeper's daughter. His cousin he remembers only as a childhood playmate; his wife he remembers not at all. The women have a choice
- to leave him where he wishes to be or to 'cure' him. It is Margaret who reveals a love so great that she can make the final sacrifice.
