I don't remember a lot of the details from the film at all, but one scene stands out rather vividly.
The main character is a young man, in his 20s/30s, visiting his dying father at the hospital. He is approached by another man who is a family member of some sort, with whom he gets into a disagreement. The only "quote" I remember is the protagonist's last remark, when he says something along the lines of:
"We are not family. Any family connection you and I share dies along with my father."
