A man makes a troublesome incident in the hospital, court, and church on behalf of truth. He asserts that his month will pour out only the truth, nothing but the truth, and everyone shall be drowned to death by his truth. There's a medical accident, a court fuss, and the church is finally submerging in his truth.

The film His truth is Marching on begins with a scene of a cross submerged in water. A man wanders around hospitals, courts, and churches and talks about truth. While we are curious about what truth he tries to tell, the film answers and throws another question back. Questioning continues after the movie ends. The man in the film is sunken underwater, and his words die. But the truth resurfaces because, as always, the truth will be revealed someday. (LEE Hyunkyung)
