Mancha is an easygoing bike messenger with no big expectations in life. His only cares in the world are riding his motorcycle, being with his girlfriend Clara, and hanging out with his fellow messengers. His carefree existence is disrupted one day when they all get fired and Clara announces that she is moving to Horse Island - a place that doesn't allow any motorcycles. Faced with no other job prospects, Mancha forms a debt-collecting biker gang with his messenger buddies to try and preserve his way of life and win Clara back.
