Star Trek: Section 31

It's a new movie to be released January 24th staring Michelle Yeoh. Here's some history of the organization to prep beforehand. See the link for a lot more.

"Section 31 was an organization which claimed to protect the security interests of United Earth and, later, the United Federation of Planets. During the mid-23rd century, they were considered a critical division of Starfleet Intelligence, while by the 24th century, they were believed to be a rogue organization not considered part of the Federation, but were in fact still part of Starfleet Intelligence."
