The artist, a man disillusioned with life, seeks inspiration as he wanders through the foggy streets of the city. On the other hand, the detective, who has perfected the art of solving crimes, lives each day as if it were an adventure, but he begins to realize that the time for being a mere observer has passed.
Upon meeting a mysterious woman who seems to have vital information about an unsolved case, both men quickly find themselves drawn into a tangle that will take them into a labyrinth of identity and crime. From a posh nightclub to the shadowy world of organized crime, the two men are forced to join forces. However, as they delve deeper into this unsettling mystery, the line between reality and fiction becomes blurred. It turns out that the detective has a past he is unwilling to share, and the artist, finding his muse in chaos, begins to question the morality of the limits he is willing to cross.
In a bewildering climax, the fates of both men intertwine in a finale that will change their lives forever, revealing that sometimes, the greatest mysteries are the ones we carry within.
