Washington D.C.'s street grid and monuments have long fueled claims that the city was designed by Freemasons to encode occult symbolism into the nation's capital. This film, the second volume in the "Secret Mysteries of America's Beginnings" series, lines up researchers who argue for hidden meaning against Masonic apologists who defend the design as civic pageantry rather than ritual. It walks through the specific claims point by point: a pentagram allegedly traced in the streets north of the White House, a Masonic square and compass said to extend from the Capitol to the Washington Monument, and zodiac signs, unexplained faces, and pagan god and goddess imagery worked into public buildings. The film notes that every major cornerstone in the capital's early construction was laid by Freemasons, and uses that fact as the hinge for its central question, whether the city's layout reflects ordinary Enlightenment-era design or a deliberate symbolic program. Both sides get airtime, and the film leaves the argument open rather than settling it.
