Big Boss #57

In "J'ai rencontré le 1er Martien," a mysterious flying saucer forces a plane to crash, leaving its sole survivor, Jo, face-to-face with the first Martian ever seen on Earth. As the alien attempts to silence Jo by exploiting the deepest fears of the other passengers, the line between reality and terror begins to blur.

In the 1982 sci-fi anthology Big Boss #57, "La cage mystérieuse" follows Professor Kenton, a man whose experimental rocket has just returned from space, now demanding a massive cage be constructed—without revealing why. The mystery deepens as he insists on secrecy, leaving the builder, and readers, to wonder what purpose such a structure could serve.
