Unable to cope with his new physical limitations and surging insecurity, Andreas becomes increasingly bitter and emotionally distant from his beautiful wife, Liv. Seeking to ease the mounting domestic strain, Andreas invites Wagner, an older, enigmatic handyman, to live on their isolated rural property to help with house renovations and daily tasks. However, the arrangement quickly turns toxic. Wagner begins to craftily manipulate the couple's vulnerabilities, ultimately initiating a highly intense, secretive extramarital affair with the sexually frustrated Liv. As Andreas watches his control slip away, he uncovers the crushing infidelity happening under his own roof, igniting a dangerous, claustrophobic psychological game of jealousy, submission, and ultimate revenge.
