An elderly man, known for his unique ability to survive on the Moon's far side, lives in isolation above a mining colony. His name is Pop Young, and he is haunted by fragmented memories of a past life, particularly concerning a man named Sattell, who is linked to a traumatic event that erased his memories. Pop's existence is marked by the harsh lunar environment, where he performs essential tasks for the mining operation, including receiving supplies and maintaining the landing field. Pop's life revolves around recovering his lost memories, which he believes are tied to Sattell. After a traumatic incident that left him with a severe head injury, Pop awoke in a hospital with no recollection of his identity or the fate of his family, who had been murdered. As he attempts to piece together his past, he becomes increasingly fixated on Sattell, who seems to trigger vague recollections of his wife and children. The mining colony, located deep within a massive lunar crack, is a grim place where workers struggle with the psychological effects of low gravity and confinement. Sattell, now living underground, is tormented by the presence of Pop above him, fearing that Pop's memories will lead to his own exposure and downfall. Sattell's paranoia intensifies as he writes desperate letters to Earth, seeking a way to escape his past and the looming threat of Pop. An unexpected event occurs when a luxury passenger spaceship is launched to the Moon, promising a thrilling experience for wealthy travelers. However, the journey proves too overwhelming for the passengers, leading to chaos and hysteria. This event indirectly affects both Pop and Sattell, as it draws attention to the Moon and its dangers. Pop continues to work diligently at his shack, using his time to sketch memories of his family, which he hopes will help him recover more of his lost past. His artistic endeavors become a means of reconnecting with his former life, and he discovers a talent for drawing that allows him to visualize his memories more vividly. The story takes a turn when a red-headed man arrives in a stolen spaceship, demanding that Pop provide him with the valuable diamonds mined from the lunar colony. This man is connected to Sattell, who has orchestrated a plan to retrieve the diamonds and escape. Pop, realizing the danger, devises a counterplan to protect himself and the mining colony. In a tense confrontation, Pop manages to outsmart the intruder, leading to a catastrophic explosion that destroys the spaceship. This act not only eliminates the immediate threat but also serves as a catalyst for Pop's memory recovery. As he reflects on his past, he feels a renewed sense of purpose and determination to reclaim the memories of his family. Ultimately, Pop's journey is one of resilience and the quest for identity. Through his artistic expression and the confrontation with his past, he begins to piece together the fragments of his life, finding solace in the memories of his loved ones. The story concludes with Pop embracing his newfound clarity and the hope of fully reclaiming his lost youth, symbolized by his artistic creations.
