The actual videos can be ordered from ABC news. But I caution you. Your emotions could well lead you into serious issues having seen this story. I was emptied. It was unbearable. It still is. Yet it happened and to some extent still happens today.

Here is the summary:

June 10, 2002 - In the mountains of northeast China, an hour's walk into the forests, a family once hid underneath the earth.

Three years ago, Kim Kan-Su and Kim Young-Hee lived here with their 5-year-old son, Young-shin, in a hole in the ground, hiding from police. Their crime, in the eyes of China and their homeland, North Korea, was simply that they left their famine-stricken country to look for food.

Their underground hideout was only a couple of miles from the North Korean border, but it was one of many "homes" they had in the mountains since they fled North Korea.

Chinese police are paid a bounty to capture refugees like them and return them to North Korea. The Kims lived with the knowledge that if they were sent back, they would be labeled as traitors and possibly face execution.

"Though we don't have a house, living like this in hiding, at least we eat rice, which is rarely available in North Korea, even for well-off families. We just hope we don't get caught," Young-Hee, the mother, told Korean-American filmmaker Kim Jung-eun at the time.

"Everything else is fine, except for the fear and distress," said Kan-Su, the father.

In the forest, surrounded by caution and living in fear, the Kims tried to keep some sense of a normal family life for their young son. Kan-Su taught his son about the animals, and showed him how to set traps, to catch rabbits and birds. He used some of the game to trade for rice and vegetables at a local village.

Kan-Su worked at a tobacco farm an hours' walk from his hideout. His labor there was illegal and he received no pay, but he was compensated with a small amount of rice, which he brought back to his family every three days or so.

The family still bore the scars of their situation though. Malnourishment from the famine of North Korea stunted Young-shin's growth, and his parents mourned for their broken family.

When the Kim family first came to China, they had three children and Young-Hee was pregnant with a fourth. But they could not feed or educate them properly, hiding in the forest, and one by one, they had to give their children away.

The baby boy who was born in the hideout was first given to a childless Chinese family. Later, the Kims reluctantly handed their two girls to an orphanage. They considered it the girls' only chance of ever receiving a minimum standard of decent nutrition and education.

Soon, the Kims realized they could not provide enough for Young-shin either. So three years ago (1999), the Kims gave away the last of their children.

Is any sorrow like the sorrow of a bereaved parent or child? Can we not love God more as we see how He unselfishly, unflinchingly gave His only Son for us?

Where are the Kims now? Did the children return to anything like normalcy? Was the family united? And what of the thousands of other "Kims", scarred forever by the tyranny in Pyongyang?
