A pair of mice are trying to board Noah's Ark: Finny, a charismatic poet who suffers from terrible stage fright, and Tito, a talented and charming guitarist. When it rains, only one male and one female of each species are allowed on Noah's Ark. With the help of a clever cockroach and good luck, Finny and Tito sneak aboard and together avoid a confrontation between the ark's carnivores and plant-eaters. All the while, the animals perform a series of classical songs inspired by world-famous poet Vinicius de Moraes. Can these talented travelers use music to break the tension and help these trapped creatures survive 40 days and 40 nights together?
