Watergate plus 30

What lessons has America learned from Watergate? Thirty years after the most infamous break-in helped pull down President Richard Nixon, all of the facts are still not in. But as this compelling documentary shows, Watergate remains a nearly unbelievable tale of ordinary men corrupted by power and their desire to retain it. Interviews with investigator Sam Dash, co-conspirator John Dean, and journalist Bob Woodward recreate the history and speculate on the effects. [PBS website].
