A Letter to My Dad is a film that is best described as a drama-documentary hybrid. It is based on real events but is structured like a live-action feature film. The central theme is the relationship between a particular father and son, or more precisely, their communication issues. The characters are Mate (70) and his son Milivoj (44). The film has three distinct sections: an intimate confession from the son, a portrait of the father and a confrontation between the father and son.
