The global cyberwar is heating up and the stakes are no longer limited to the virtual world of computers. Now, thanks in part to secret documents released by Edward Snowden, the true scale of the National Security Agency's scope and power is coming to light. Besides spending billions of dollars to ingest and analyze the worlds' electronic communications, the NSA has set out to dominate a new battlefield—cyberspace. We examine the science and technology behind cyber warfare and asks if we are already in the midst of a deadly new arms race". Already, highly sophisticated, stealthy computer programs such as the notorious Stuxnet worm can take over and even destroy the control systems that regulate everything from food factories to gas pipelines, power plants, and chemical facilities—even our cars. While the destruction of Iranian centrifuges may have delayed Iran’s bomb program and forestalled an Israeli attack, the attack has opened a Pandora's Box, and now America's own critical infrastructure is vulnerable to retaliation and attack. With leading defense experts and investigative journalists who have probed the murky realm of criminal and strategic hacking, NOVA examines the chilling new reality of cyberwar in which no nation or individual is safe from attack.

Many consider it the greatest team ever assembled, in any sport. Yet even that description fails to give it proper credit for its impact. The original the Dream Team, the first U.S. Olympic team to include NBA stars was a phenomenon on and off the court. It mattered not that it dominated the Olympic competition. It won the gold medal at the 1992 Olympics in Barcelona, beating its eight opponents by an average of 44 points. What was important was that the Dream Team, gave fans a glimpse of basketball at its finest, and an entire world responded. The film is the definitive documentary of the historic 1992 USA Basketball team, featuring recent interviews with all 12 members, including Michael Jordan, Magic Johnson, Larry Bird, and Charles Barkley. Includes rare footage from USA Basketball's film library, and the untold story behind what has become part of basketball legend. Since 1992, basketball has exploded in popularity around the globe, rising to a place where it truly challenges soccer's status as the world's most popular sport. Much of that is due to the impact of the Dream Team, which attracted fans and followers wherever it went. "It was," said Coach Chuck Daly, "like Elvis and the Beatles put together. Traveling with the Dream Team was like traveling with 12 rock stars. That's all I can compare it to." And what a band it was. Start with three of the game's all-time greats: Michael Jordan, Magic Johnson and Larry Bird. Add the irrepressible Charles Barkley for a little spice, as well as seven more NBA All-Stars: centers David Robinson and Patrick Ewing, power forward Karl Malone, swingmen Scottie Pippen, Chris Mullin and Clyde Drexler and point guard John Stockton. Complete the roster with Christian Laettner, the best college player of 1991-92 and a future NBA All-Star. Opponents didn't have a chance, but they didn't care.
