To pay for his grandmother's surgery and preserve his chance to study in London, struggling student Auden accepts Stellan's offer: seduce Stellan's fiancé, Blackwood heir Soren, and make him end their arranged engagement. Auden gets close to Soren and falls for him for real. When the truth comes out, Soren turns betrayal into possession, using Auden's phone, passport, housing, and Mabel's medical care to control him. Auden escapes to Northfield with help from his friends, but Soren finds him. During a confrontation on a mountain road, Soren is struck by a car while saving Auden. In the hospital, he admits that he confused control with love and promises to let Auden go to London. Three months later, Auden agrees to one public meeting, unaware that Soren is waiting with a return ticket and a pair of handcuffs.
