Winter Visitor

Winter Visitor is a 2008 Argentine, Spanish film, written and directed by Sergio Esquenazi. It is probably the most important Argentine horror film of the last 30 years, since it was the first Argentine horror film in two decades to be supported by INCAA and therefore the first Argentine horror film to premiere in the country in 20 years, which opened the doors to directors and producers of the genre which up to that time were condemned to an under circuit.
