In a business that asks no questions, The Courier (Jeffrey Dean Morgan), is the best out there - but he wasn't expecting a deal like this. Deliver a briefcase, get a million dollars. What's the catch? Fail, and his family gets killed. The briefcase belongs to a killer as elusive as a nightmare, and so feared that the entire Underworld trembles at the mention of his name.

And with a new partner by his side (Josie Ho), it's hard to know who to trust. Hounded by hit men and hustlers, double-dealing feds and double-crossing accomplices, the Courier embarks on an impossible journey that ultimately unravels his own murky past.
