Situated in Prague, a 20-year-old Vietnamese named Song, hoped for a better future in Europe. But now in a Vietnamese district in Prague, he is trapped in a marijuana grow house and has life of a modern slave. Police rounds up the place. Song runs away on the rooftop of a condo building in a nearby district where he breaks down. Mr. Rypar (78) lives alone. He is fond of the old times, living in a strong opposition to modern world. Rypar goes up on the roof and meets Song standing on the very edge of the roof crying and the story begins.
