Submitted by Taiga
Joe and Isaac are killed in the war. Daisy (Saoirse Ronan) takes Piper and escapes the work farm to return home to be with Eddie, finding their house badly damaged by the invasion.
Soon, Eddie (George MacKay) also returns but is severely wounded. Daisy nurses him back to physical health but he remains too traumatized to speak.
The war ends and Daisy remains with Eddie and Piper, dedicated to helping Eddie heal so they can love each other again.
