For most of his life, Ignacio Carrillo has travelled the villages of northern Colombia playing traditional vallenato songs on his accordion—a legendary instrument said to have once belonged to the devil. He eventually married and left the nomadic, troubador life behind, but after the death of his wife he vows to never play the accursed accordion again, and embarks on one last journey to return the instrument to its rightful owner.
Dogged by Fermín—a spirited teenager determined to become his apprentice—Ignacio begrudgingly accepts the young man’s companionship. Together they traverse the vast terrain of mountains, lakes and deserts, discovering the musical diversity of Columbia’s Afro-Hispanic culture. Hardened by the loneliness of his itinerant lifestyle, Ignacio tries to discourage Fermín from following in his footsteps… but destiny has different plans for them.
