Quick recap
Washington, D.C., 2018. During the funeral procession of a national leader, a sniper hits a target in the heart of the capital. Bree has just been promoted to chief of detectives and must solve it or lose the job. The new president hands Cross a massive investigation, alongside the Secret Service and FBI, into a team of six highly trained assassins threatening the country. The big question is whether the shot was only the opening move of a larger attack. The ending wasn't checked against a reliable source, so it stays out.
