A five-part series that tells the true story of how Nixon's own political saboteurs and Watergate masterminds, E. Howard Hunt and G. Gordon Liddy, accidentally toppled the presidency they were trying to protect.

In 1971, Egil "Bud" Krogh was summoned to a closed-door meeting by John Ehrlichman, his mentor and key confidant of President Richard Nixon, in a secluded office in the Western White House. Krogh thought he was walking into a meeting to discuss the drug control program launched on his most recent trip to South Vietnam. Instead, he was handed a file and the responsibility for the SIU, Special Investigations Unit, later to become notorious as "The Plumbers."

The unit was to investigate the leaks of top-secret government documents, particularly the Pentagon Papers, to the press. The president considered this task critical to national security. Nixon said he wanted the unit headed up by a "real son of a bitch." He got the studious, zealous, and loyal-to-a-fault Bud Krogh instead.
