3 THINGS centers in and around a hotel where the police are negotiating the terms of a witness protection deal with the prime suspect of a big money deposit robbery and an expert on explosives, Mikael (Nikolaj Coster-Waldau). In order to agree to the deal Mikael demands three things from the police: that his former girlfriend is brought to him, that the police bring the contents of a box he has stored, and that he is served butter chicken from his favourite restaurant. The police, under heavy time pressure to get him to witness the following day, agree.
