The movie opens in a Los Angeles convenience store one late Monday night, where a smalltime drug dealer named Nick (Aaron Eckhart) is trying to decide what coffee brand to buy. His ex-lover Dallas (Paulina Porizkova) and fellow hitman Billy Hill (James LeGros) are getting impatient and tell him to hurry up. Conflicts between Nick and the cashier (Luck Hari) ensue, resulting in Dallas shooting the cashier dead. Though the three attempt to cover up the crime, they are forced to also shoot a police officer (Bari K. Willerford) when he discovers blood on the ground.
Casey has given up drug dealing for a suburban idyll in Houston, a job as an architect and a new wife. They are even planning to adopt a child. But Casey's past arrives on the doorstep in the shape of Nick, an old business partner. And all hell breaks loose!
