Jean (Lee Young-ae) on behalf of the Neutral Nations Supervisory Commission.As Sergeant Lee Soo-hyeok has confessed to the shootings, Sophie investigates why the two Koreas have contradicting accounts of events; Soo-hyeok's states he was knocked out and kidnapped while relieving himself and, waking tied up in the North Korean border house, secretly freed himself and shot three North Korean soldiers, leaving two dead.

Question: In the movie, in what year did Laurel and Hardy return to Roach for a feature deal? Movie plot title: Block-Heads Movie plot: The film opens in the trenches of World War I where Ollie, Stan and the rest of their army company are ready to go 'over the top', but Stan is ordered to stay behind to guard the trench. Stock scenes of fighting are then seen followed by the caption 'Armistice'. Twenty years pass, and Stan is still guarding the post, as shown by the huge pile of bean cans he has accumulated, and the path he has worn pacing back and forth on guard. He is found by accident (after firing on a plane he sees approaching) and is brought home, feted as a hero. Ollie, who has been married for a year to the formidable Mrs. Hardy (Minna Gombell), sees him in a newspaper and visits him in the veterans' home. He finds Stan in a wheelchair, having apparently lost a leg, and invites him home. However, Stan is in fact just resting in another veteran's wheelchair and Ollie only finds out he still has both legs after pushing him around in the chair and then carrying him. Ollie, angrily: "Why didn't you tell me you had two legs?" Stan: "Well, you didn't ask me." They reach Ollie's automobile, which he says belongs to his wife and is 'practically new', but it is boxed in by a dump truck. Stan climbs into the cab to move it and inadvertently operates the dump mechanism, burying the car in sand and leaving only Ollie's head exposed. It is then completely wrecked when Ollie demonstrates the automatic garage door at his home and allows Stan to drive the car in to test it. There is then a lengthy scene of the pair attempting to climb thirteen flights of stairs to Ollie's apartment because they think the elevator is out of order. They are resting near the top when a top hat-wearing man with a cane (James Finlayson) insults Ollie, leading him to challenge him to a fight outside. They return down the stairs, picking up spectators along the way. After settling the disagreement, the pair finally reach the top of the stairs, where they run into a brattish kid (Tommy Bond) with a football. Ollie kicks his ball down the stairwell, where it hits the face of...

Problem: Given the question: Please answer the following question about this movie plot. If it's un-answerable, please output "No answer". Question: Why were the group of Italian soldiers sent to the Greek island? Movie plot title: Mediterraneo Movie plot: In 1941, one year after Italy joined Germany against the Allies in World War II, a small group of misfit Italian soldiers is sent to a small Greek island in the Aegean Sea for four months of lookout duty. The soldiers include a lieutenant who likes art, a macho sergeant, a farmer accompanied by his beloved donkey Silvana, and other quirky people. They are not very good soldiers, but a cross section of average, independent men. The soldiers anticipate attack from outside and on the island and take all sorts of inept precautions. They find a small town with no people. That night, they see bombing on the horizon and realize that the ship that would pick them up has been destroyed. Then mysteriously, people reappear in the village: the villagers say they hid because the Germans had taken all the men, but having seen that the Italians are absolutely harmless they have decided to return to their lives. It isn't long before everyone's sunny nature appears. The Italian soldiers, unacquainted to a war they clearly don't sense as theirs, are absorbed into the life, heat and landscape of the idyllic island. The local orthodox priest asks the lieutenant, a Sunday painter, to restore the murals in his church. Two soldiers, who are brothers, befriend a lovely young woman, a shepherdess. Sergeant Lo Russo, the only member of the crew with a fierly spirit for war, takes up folk dancing, and the shyest of the soldiers, Farina, falls profoundly in love with the island's single, very overworked prostitute, named Vassilissa. In their old age three of the men are reunited on the island to close the film.[3]
