A Buenos Aires Ghost(2009)

Original title: Fantasma de Buenos Aires

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.
