Inspired by the Jacobean tragedy The Changeling by Thomas Middleton and William Rowley, it follows a young female Cambridge graduate called Anjika Indrani (Parminder Nagra) and attempts by her father Satvick (Vincent Ebrahim) to force her into a marriage with Hardik (Sargon Yelda) despite her existing happy relationship with Alex (Ben Aldridge).
It also stars Ray Winstone as Don Flowers, Satvick's chauffeur, and James Floyd as Jaiman.
Anjika's father, Satvick, forces her into an arranged marriage with a business associate's son, Hardick.
Satvick's chauffeur, Don Flowers, realises Anjika is not happy with her father's plans and says he will help her out, on the condition she spends the night with him.
Reluctant, she visits the hotel room Flowers booked and allows him to flirt with her, touch her and smell her, before the pair have sex.
Things complicate, however, when Alex and Anjika reveal their relationship and her parents strongly approve, even arranging a marriage for the two.
Anjika becomes stressed, realizing her heart belongs with Flowers despite the age difference, yet she's in denial and insists she still loves Alex.
Overnight ratings estimated that "Compulsion" was watched by 4.7 million viewers, approximately 22% of the total television audience.
