The Earth in the far future, where humanity no longer exists. Cats that survived in the debris left behind by humanity have evolved into intelligent beings. The three cats, Kitz, Tutti, and Pepe, are working as cleaners at NYASA. Weird signals were detected in the largest space junk in Earth's orbit (Humans called it the International Space Station)! Today's mission is to investigate the space station floating like a ghost ship! Kitz, Tutti, and Pepe meet an A.I. on the space station that has endured tens of thousands of years of solitude. The A.I.'s wish is to leave Earth's orbit and go on an endless expedition into the far reaches of space. Will the cats be able to fulfill the A.I.'s wish?
