When Betsy visits Arlene at the Watergate Motel, the two accidentally stumble into the middle of the infamous Watergate robbery. In order to keep them quiet, Nixon (Dan Hedaya) appoints them as honorary dog walkers. As they travel in and out of the White House, their seemingly innocent actions start a chain of events that may eventually lead to Nixon's resignation as president of the United States.
