This is the story of a woman who vanishes - one Sunday morning. Her name is Betty, and her disappearance is as enigmatic as it is mysterious. Did she run off? Even if she wasn’t happy with her marriage, Betty would never have abandoned her two children. Was she murdered? There’s no trace of a struggle, and her body hasn’t been found. Who would’ve killed Betty? How? And why? For her lover, Frank, there’s no doubt about it: Betty was murdered. And everything seems to point to her husband, who doesn’t seem too upset about his wife’s disappearance. Frank starts tailing him. But the truth is - it’s hard to get to the truth, which is hidden somewhere in the deep ambiguities of three figures who turn everything we think we know upside down.
