Tensions mount as emotions run high and taboo subjects are explored such as incest and politics. As their dinner table conversation begins to escalate into physical and verbal altercations, the family awaits the arrival of a friend named Hallewyn. When the night is over, will their friend still be joining them?

A comic strip detective and a superhero are hired to investigate separatedly the successive murders of CEOs within a real life corporation symbolizing a nation, while subversive groups and members of the establishment lead a war for power.
