In a world where animals have taken over and humans no longer exist, two mice, Vini and Tito, embark on a journey to board Noah's Ark. With Vini's charismatic poetry and Tito's charming guitar skills, they attempt to sneak their way onto the Ark. As the ship sets sail for 40 days and 40 nights, the pair must find a way to avert tension among the carnivores and plant eaters on board. With the help of an ingenious cockroach, they bring harmony to the Ark through classic songs inspired by the world-renowned poet, Vinicius de Moraes. Will they succeed in their stowaway adventure and help the animals survive together?
