Actor-director Daniel Yoon draws on his own experience with head trauma to create this low-key comedy drama. Yoon plays Matthew K., a hired killer who aids large corporations to liquidate their assets. On the job, he gets struck by a car, resulting in a serious head injury. Instead of returning to the biz, he holds up in his San Francisco apartment and starts to take in life. He beigns by undergoing some new age holistic therapy while befriending a comely East Berliner physics student who lives downstairs. Post Concussion was screened at the 1999 Vancouver Film Festival.
