Laura is a beautiful woman in her early forties, married to a husband who's always away on business. She grows to realize she won't be young forever, obsessing about her wrinkles; she tries to hide them every moment she gets. One night, in a moment of madness, she slips into her 18-year-old stepson's room, crosses a boundary, and engages in an act that can never be undone.
This event results in a relationship of unbridled passion between a stepmother and her stepson, which escalates even more once she finds out he'd been lusting after her for months. When she suspects her husband of cheating, she sees it as justification. But all isn't as it seems with his alleged mistress as past secrets comes back to make a full reveal, changing the meaning of everything she thought was true before.
