One-person invasion attempt

In August 1990, an unemployed french nuclear physicist named André Gardes attempted a singlehanded invasion of Sark, armed with a semi-automatic weapon. The night Gardes arrived, he put up signs declaring his intention to take over the island the following day at noon. He was arrested while sitting on a bench, changing the gun’s magazine and waiting for noon to arrive, by the island’s volunteer constable. 

I want to make this film.
