Milo, a naughty and adventurous little wolf, grows up thinking that one day he will suddenly become a ferocious wolf. When he discovers that this will not happen by magic and that he must train all day, like the other wolves in the pack, Milo asks himself: will I have to stop being myself in order to be fierce? Milo's friends know him well and know that he won't be happy training like the others, so they decide to help him. Discover how Milo finds his own path and becomes a strong, agile, fast, cunning, stealthy wolf, who jumps very, very high and can make his howl carry across the mountains.
