Wilee is one of 1,500 bike couriers in Manhattan who rides on the edge by having a bike with no brakes. On this day, Wilee has a delivery that is so valuable that a corrupt NYC Detective, who needs the money, begins to chase Wilee throughout the city to get it before the envelope is delivered. Among the bike couriers in New York City, no one is more determined and reckless than Wilee, an ex-law student more comfortable on his brakeless bike than in a suit. One day, a Chinese foreign student named Nima arranges for him to deliver a vital envelope across the city. Unfortunately, a crooked cop, Det. Robert Monday, has a desperate need for that envelope himself and won't take "No" for an answer. Now, Wilee finds himself relentlessly pursued by Monday and others in a situation becoming more complicated and dangerous by the minute. Together with his friends and rivals, Wilee must discover the secret of this dangerous delivery and make it through a gauntlet that will require all his cunning, daring and courage to survive.
