Taking note that a lieutenant with the same name as her husband has died in the war, she presents herself to his aristocratic parents as his widow and soon ingratiates herself.

When Philip threatens exposure the cousins fight causing John's war wound to reopen. Thinking that he is dying, John summons a priest, who solemnizes his union with Cicely. John later recovers and the two resume their life together.
