How do a successful surgeon and a Senator's administrative assistant find themselves with Lafayette Park as their residence? Dr. Mark Puccini and Maddie ChapelIe are among the homeless who call the area across from the White House home. Following a turbulent first meeting in the park, they become allies with a common goal. Mark suffered periods of blackout, which ended his career as a physician, beginning his life on the streets of Washington. In an effort to escape a sexually harassing boss and a traumatic attack, Maddie relinquished her career in Boston and her identity. Together, they encounter the powerful Project 1947, whose goal is to control the population by intervening in politics through assassinations and worse. Working with Senator Pope, Mark and Maddie develop and advocate health care legislation for the indigent. The Senator's drug-addicted wife and his womanizing bring political chaos to the effort. Project 1947 becomes a force to be reckoned with up to the level of the President. Elements of suspicion and dismay lead the Street Doctor and Maddie toward an uncertain future.
