Lore Rivera was married to two men at once, until on a baking hot day in 1986, one of them found out and shot the other. A secret double life, a tragic murder. That's the story the world knows. It's not the story that fascinates Cassie Bowman. Carrying the weight of her own family tragedy, true-crime writer Cassie wants to know more about the mysterious woman at the heart of it all: Lore. And to her surprise, Lore is willing to talk - about how a dance became an affair; how a marriage became a murder. As the two women grow closer, Cassie finds she can't help but confess her own darkest secrets. But when it becomes clear that there might be more to the night of the murder than anyone realised, can either woman face up to the thing they've been hiding from… the truth?
