Gathering her close friends together, she's determined to clear her name. Ruth's POW son suffers a life-changing injury just as her own cottage takes damage in an air raid and Penny's estranged little sister unexpectedly turns up, having run away from school. Together with the ongoing thefts of items of clothing and surprise personal revelations, these all threaten to hamper their investigation. In spite of the worsening war situation, they must band together to rise above their troubles and prove love and friendship is worth fighting for.
