A disgruntled man, Allen, finds his life unraveling as his career and marriage fail to meet his expectations. Drowning his sorrows at a bar one night, he encounters a mysterious stranger, Jonas, who appears to be a professional hitman. After a few drinks and driven by his frustrations, Allen jokingly creates a "hit list" of people he wishes were out of his life, including his wife and boss. Initially, the encounter seems to be nothing more than a drunken fantasy born out of Allen’s dissatisfaction with life.

However, when the people on Allen's list begin to meet untimely ends, he realizes with horror that Jonas took his venting seriously and is systematically eliminating the names mentioned. Allen must now race against time to try and stop the hitman before he completes the list. Desperate to undo the consequences of what he once considered a harmless venting session, his moral compass is put to the test as he's thrust into a deadly cat-and-mouse game.
