Situated in Prague - while the same story may easily happen in any city in Europe or North America that attracts immigrants and is big enough to shelter stories we never get to know. Song, 20-year-old Vietnamese, 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 crushes in. Song runs away on the rooftop of a condo building in a nearby district where he breaks down. Mr. Rypar (75) 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.
