L'Horloge maudite 024

Michael and Tania's father has just bought the clock he had always dreamed of. Of course, they are strictly forbidden to touch it. Michael has an idea: what if he damaged it, making his little sister take the blame? He would finally get revenge for all the bad tricks she has played on him. But Michael is unaware of one detail: this clock allows you to go back in time. By twisting the cuckoo's head, he will reverse the course of time. Definitively?
