How much of our time belongs to us, and how much do we give to family obligation? Casual Sunday is a fiction short film that narrates a day in the life of Damián (Matías Dinardo), who faces an internal conflict between accompanying his sister Karen (Jimena López) to spend Sunday with the family, or taking the day for himself and getting to know Martín (Lucas Baca Cau), a neighbor passing through his building.
