The Night Agent follows Peter Sutherland, a low-level FBI agent assigned to a quiet post in the basement of the White House, where his sole duty is to monitor a phone that never rings until one night, it does. On the other end is a panicked civilian, drawing Peter into a deadly conspiracy that reaches the highest levels of government. As he fights to protect the caller and uncover the truth, Peter must navigate a maze of spies, traitors, and long-buried secrets where trust is scarce and every decision could be his last.
