Epi Dalmau is a desperate man. Early one morning, he carries a duffle bag into a dingy bar in a rough neighborhood of Barcelona. Four other people are in the bar: his brother Alex, his good friend Tanveer, the bartender, and a Pakistani man who wandered in to use the restroom. Epi grabs a hammer out of his duffle bag and attacks Tanveer. After a brief struggle and a couple of blows, Tanveer lies dead on the floor and Epi flees the bar. Alex and the bartender plan to find and protect Epi, while blaming the murder on the unfortunate Pakistani man, who was simply in the wrong place at the wrong time.
