Tommy Akhtar, the son of immigrants, works as a snoop in London. Melody Chase visits him to ask him to look for her missing roommate Natasha, a Russian prostitute. Tommy steals a keycard from the cleaning staff and sneaks into the hotel room where she met her last client but only finds the dead body of Usman Rana, a Pakistani businessman. Tommy takes the dead man's mobile phone as evidence, calls the police with an anonymous tip about the murder from a payphone at a bar, and has the phone's PIN cracked by Avid, a young weed dealer whose mother wants Tommy to help get out of trouble. Two of the last calls made from the phone were to Hafiz "Lovely" Ansari, a childhood friend of Tommy's, to discuss an investment. Tommy visits him at his home and Lovely asks him to investigate the matter because the murder is scaring away other investors.
