In the twenty-second century, humanity encounters the enigmatic after a space probe detects a colossal cylindrical object speeding through the solar system. Named Rama, the object is soon identified not as an asteroid, but as a gargantuan interstellar spacecraft. A team of astronauts embarks on a daring mission to breach the alien vessel where they encounter wonders and mysteries far beyond human comprehension. As they explore the vast internal landscapes and complex machinery, they find no signs of life—only the automated guardians of the ship. The purpose of Rama's journey and the origins of its creators remain shrouded, leaving humanity to ponder whether they have been visited by benevolent explorers or witnesses to a vessel of incomprehensible indifference.
