In this mysterious and dark city, crime is commonplace. Bill (Simon Pegg), a teacher suffering from a terminal illness, tried to commit suicide, but he could not. One day, Bill met Anne (Magro Robbie), a beautiful blonde waitress, in a late-night cafe. The two of them started a conversation about "how to commit suicide successfully" and developed a strange friendship... In another corner of the city, two assassins (Max Irons and Dexter Fletch) who were carrying out dangerous missions were running back and forth between cities in order to get a high reward, eager to find clues to the assassination target... However, the appearance of the night guard (played by Mike Myers) unexpectedly brought these two seemingly unrelated characters together. As one crime after another occurred, the mysterious pasts of the people and the intertwined love and hatred were gradually revealed. In the end, they found themselves all involved in a complicated criminal plan. Can they find out the truth? And who is the mysterious mastermind behind the incident?
