Dr Yvonne Carmichael (Watson) experiences a powerful attraction that begins her first and only act of infidelity in a long marriage - a completely out-of-character moment of madness.
Apparently happily married, a mother of two grown-up children, and highly respected in her work, Yvonne believes she is in control of her life and can keep this act, and the affair that follows, separate and secret. But despite the care she takes, her actions have consequences that spiral into greater deceit, and ultimately, a life-changing act of violence.
