Set in France beginning in 1918, Léon and Louise is the love story of two teenagers who meet as World War I is drawing to a close. Separated during a German artillery attack, each is severely wounded and believes the other to be dead.
10 years later, both are living and working in Paris. They catch a glimpse of each other on passing metro trains. Léon is married now with small children, but his wife encourages a search for Louise, knowing that their marriage can’t move forward while Léon’s heart remains in the past.
