The young husband and wife evade capture for as long as possible, until they are cornered by Nazi soldiers with tracker dogs. Izzy's disguise works. The couple are assumed to be two escaped British soldiers and transported to a PoW camp. However, their true test has just begun as they face terrible living conditions and the constant terror of Izzy's exposure. But in the midst of unimaginable horrors comes hope, for the young couple are befriended by a small group of fellow prisoners. These men become their new family, willing to risk their lives to save Izzy from being discovered and shot.
