From the liner notes

Erik has one week to live. He must pay Luis, the head of a dangerous Colombian drug cartel, or he will die. Erik turns to the only person he knows who can reckon with Luis's empire—his brother, K, the leader of an L.A. gang. And reckon he does: K hatches a plan to rob an armored truck, in broad daylight, on a busy street corner. What happens next is an action-packed story of guns, greed, betrayal, honor and bond between brothers and thieves.
