It’s 1969, and the summer of love still lingers in London, but Gilda is haunted by her wartime past. She walked out on her son, Reuben, when he was just a boy and fears he’ll never forgive her. When he marries a small, blonde gentile, she takes it as the ultimate rejection. Her cold, distant son seems transformed by love. What does his new wife have that she doesn’t?
As Gilda’s obsession builds, she starts to follow her daughter-in-law, copies her hairstyle and breaks into the newlyweds’ home. Watching her son and his wife stumble through their first few months of marriage, she is forced to reflect on how she ended up so alone. And when new and shocking truths come to light, she has the opportunity to put the past to rest. She must decide between doing what is right and the tantalising prospect of revenge.
