The plot is about a fat guy in France. Two terrorist kidnaped Secretary-General of the United Nations – a Japanese. The police thought he was a terrorist and arrested him and lock him in a room with a real terrorist. There was a female Japanese who “torture” him. Then he accidentally helped the terrorist commited suicide. The 2 terrorist who was keeping the Secretary-General of the United Nations wanted to exchanged the Secretary-General of the United Nations for the other one. The police force this guy to disguise as a terrorist. And because the terrorist had never met each other before so they didn’t know he was fake.
There was a sub-character – a Frecnh special force who leaked the information about the kidnap and was dismissed. He then had to picked his mom up in the airport. They were roaming and accidentally came to the exchanged place and helped the terrorist escaped
In the and, the 2 terrorist found out this guy was fake and one of them threw out a grenade in an Adult Club. The guy and the female Japanese survived live happy forever after
That some detail I remember about it
P/S: the terrorist was Muslim/Islam or something
