It's a very important day for the cat family—the tenth anniversary of Mom and Dad's meeting. Everyone is excited for the holiday, but first they need to stop by Grandma Isolde's science center to pick up a special gift. There, the kittens and their parents accidentally discover an old sofa, which turns out to be a time machine, and suddenly their exciting journey through time begins. The kittens and their parents will travel through the Stone Age, the ancient world, the Middle Ages, and the Industrial Age, and even witness their mom and dad meet on this day, exactly 10 years ago.
In each era, they will face challenges, dangers, and fun adventures—from chariot races to rescuing their mom from a medieval king's castle. But to return home and celebrate their anniversary, the kittens and their parents will not only have to travel through time but also play a key role in their own love story.
