The Foreigner

Minh Quan runs a Chinese restaurant in London with his business partner Lam. When his teenage daughter Fan is killed in a clothing store bombing, he seeks revenge. The bombing is claimed by a group calling itself the "Authentic IRA". Failing to get the names of the bombers from Scotland Yard, Quan next focuses on the Northern Ireland deputy First Minister Liam Hennessy, who speaks publicly about his status as a former IRA leader while condemning the bombing. Quan eventually leaves for Belfast and seeks out Hennessy, who claims to have no knowledge of the bombing or its perpetrators. Quan does not believe him and sets off a homemade bomb in Hennessy's office as a threat unless he gets the bombers' names.
