After four men arrived on Mars, they're trying to impress the locals that they've come from Earth. The Captain of the group tried to talk to Mrs. Ttt, who was the first to communicate with him, but she couldn't because she was too busy. She tried to get her husband to communicate with them, but she couldn't. So she sent the Captain and his men to her neighbor, Mr. Aaa. The men tried to communicate with him, but he got very upset at Mr. Ttt for sending the men to him and he plans on killing them. Mr. Ttt then sent the men to Mr. Iii. On the way to Mr. Iii's they ran into a little girl and told her about how they came to Mars. She told them that they should go to Mr. Iii. Once the men got to Mr. Iii they told him that they came from Earth and expected to get a "congratulations". Instead, they were given forms sign for euthanasia, something that they didn't know about. They were also given the key to a house and were told to go Mr. Xxx. Once they got to the house, they told the Martians there the same story, and they got a different response. There were lots of clapping and cheering. After the cheering died down, they told the men that they were from Earth, too, but they actually weren't, they were just making up the places where they came from. They realized that they were in an insane asylum because of how the patients reacted to the four men. Then they started to see Martians doing unusual things like embedding into a crystal pillar and turning into gold. Then Mr. Xxx, the doctor, came and told the men that only the captain is insane, then the captain tries to prove Mr. Xxx that he's not insane by telling him his story about how he got to Mars. Mr. Xxx didn't believe him, so he tried to convince him that he's not insane by taking him to the rocket. Mr. Xxx still didn't believe him so he killed the captain. Then, Mr. Xxx killed the three men because he thinks they're insane, too. Then he thinks that he's insane because he was still in the rocket so he killed himself.
