In what's almost completely a two-character play, Toma learns that a rooftop sniper has taken 12 shots at 12 cops -- and has scored on every hit. But none of the victims has been seriously injured. Toma tries to figure out the gunman's motivation in a definitely-do-not-try-this-yourself way -- he takes a rifle, runs across the rooftop himself under heavy fire from the cops (who have been ordered to miss) and nose-dives into the gunman's wheelhouse, a control room for the building. His so-called mission is to "help" the gunman go after more cops. The gunman doesn't believe that for a minute (would you?), but Toma gets him to talk and tries to find out his motivation. When Toma finds out that the gunman has been playing it so that the cops -- who are hiding out directly underneath the wheelhouse -- are about to get 12 hand grenades dumped live right onto their heads, he must fast-talk the gunman into realizing it's a futile gesture.
