The Ballad of Oppenheimer Park is a film that celebrates the everyday life of a group of Indigenous people, exiles from Canadian reserves, who, over a fleeting summer, hang out in a contested park in Vancouver. Through direct participation in the filmmaking process, the day to day becomes a ceremonial space in the ongoing confrontation against law and order.

Assassin Robert Rath arrives at a funeral to kill a prominent mobster, only to witness a rival hired gun complete the job for him -- with grisly results. Horrified by the murder of innocent bystanders, Rath decides to take one last job and then return to civilian life. But finding his way out of the world of contract killing grows ever more dangerous as Rath falls for his female target and becomes a marked man himself.
