A comedy about the relationship between a modern, shy, young man and the spirit of a violent knife-killer murdered in 1920. They make a pledge: the latter will tell the former what exists beyond death if he allows him to inhabit his body for a whole day. Thus, the ghost will go around an unrecognizable twenty first century Buenos Aires to uncover the causes of his own death.

In a dark and decadent city, Sean Fallon - a corrupt cop - will have to face his own demons to put an end to a series of brutal rapes and murders of the most weirdest kind. With the help of the local pimps, headed by Chance, Fallon will go the hunt for the serial killer, that may in the end not be human!
