A black metal band it is about to split up. In their way to one last gig at Hellfest festival an accidental death triggers numerous misadventures to four metalheads.
One morning, Lily and Ben wake up side by side in bodies that are not theirs. And Magalie, a little girl in the body of a tall, bearded, awaits them in the guest room. This is the beginning of an incredible adventure, sometimes initiatory, where the bodies and identities will be reversed at the option of a simple hug.
