Tourists are flooding to Cambodia's "8th wonder of the world," the ancient temple complex at Angkor.

But human rights groups say the evictions are forced, illegal and target families who've worked the land for generations. Many say they're now debt-ridden and struggling to survive. Jill McGivering travelled to Angkor to meet those at the heart of the crisis.
