Beware of Dog tells three strange and possibly interconnected stories that all take place over the course of a single day in Montreal's Mile End neighborhood. A woman returns home to find her boyfriend has stashed a mysterious corpse in their basement; a man develops a relationship with a missing cat and a young woman tries to discover why her friends keep disappearing into an old apartment building. Beware of Dog is an non-traditional narrative film playing with ideas of isolation, anxiety and fear that strike a group of young Anglophones living in Montreal.
