It was the "puff" seen around the world: 13 million people watched a YouTube video of two-year-old Aldi, an Indonesian boy, puffing hungrily on cigarette after cigarette with his family looking on. But while many viewed the video with amusement and perhaps some shock, "20/20" traveled to Indonesia to find that Aldi is just the tip of the iceberg, just part of a much larger story. In fact, it is estimated that nearly 60 million people smoke there, and smoking rates are rising, including among the young in Indonesia. According to some reports, at least a quarter of Indonesian children over age three have tried cigarettes, and "20/20" cameras documented video of grade-schoolers and other toddlers smoking just like Aldi.

ABC News' Dan Harris reports that the country is in the throes of an unchecked, uncontrolled tobacco habit where, as soon as someone steps off the plane, they are bombarded with cigarette ads. How � and why � is this happening, and what is the role is an American tobacco company in all of this? Also, what happened to Aldi after he attended rehab to kick his two-pack-a-day habit? "20/20" airs on FRIDAY, SEPTEMBER 9 (10:00-11:00 p.m., ET) on the ABC Television Network.

Also: Six months after the towers fell in lower Manhattan, filmmakers began a decade-long project entitled "Rebirth" to document the full cycle from unimaginable loss to new hope and revitalized dreams. "Rebirth" simultaneously tracks the emotional transformation of people whose lives were forever altered on 9/11 by injury or loss while using minute-by-minute time-lapse photography of the construction evolution of Ground Zero. The combination of the human and physical rebirth offers a glimpse into how trauma, grief, anger and chaos can grow into hope and purpose. Elizabeth Vargas reports.

"20/20" is anchored by Elizabeth Vargas and Chris Cuomo. David Sloan is executive producer.
