It's the twins' first sleepover! Flo and Ludovic have permission for some friends to spend the night, and they're planning to go to the fair together the next morning. When it's finally time for bed and Dad turns off the light, Ludovic becomes unusually quiet. He has a secret! The other children snuggle into their comforters, but Ludovic, frightened of the dark, hides under his. Suddenly, from under the blanket, he hears a noise and peeks out. One by one, the dogs printed on the comforters come to life! One of them, a dog named Dude, approaches him. Hearing some strange noises, Flo and her friend climb to the top bunk to see what s going on. They can t believe their eyes! Ludovic s furry friends are there to help him face his night-time fears. The kids can sleep peacefully, knowing the friendly guard dogs will look out for them and be not only the keepers of the night but also the keepers of their fears.
