That's your movie right there. Your Finnish son takes a liking to hip hop and decides to learn more about it on the internet since he lives in Finland and has no one to talk to about it. No one really looks like him. He feels a little out of place. His mother loves him but something is missing. Also, his dad isn't around to teach him about that boom bap.
Eventually, he stumbles upon the coli archives. This is his home. Although these posts are years old, he gets them. His world is starting to make sense. At first he spends his time learning about the dangers of sharing girls and what people thought of Jay before he died. Then he stumbles on a thread of funny stories by a poster named General Mills.
He loves the stories, but he knows there are a finite number of them so he rations them. One story a week and they will last an entire year. As he reads the stories the audience sees his imagination. The stories are brought to life. When the year is almost up he comes across a story where General Mills is in Finland. His expression changes as he reads.
He vows to find his father. Final scene is
Finnish Mills booking a ticket to America wearing a Jaguars hat.
