Official synopsis
"In episode one of this new series, written by Mark Gatiss, Sherlock waits to see where Moriarty will make his posthumous move.
One mysterious case in particular baffles Scotland Yard - but Sherlock is more interested in a seemingly-trivial detail. Why is someone destroying images of the late Prime Minister Margaret Thatcher? Is there a madman on the loose? Or is there a much darker purpose at work? Something with its roots deep in Mary Watson's past..." reads the synopsis via Spoiler TV.
Meanwhile, "Sherlock" creators Mark Gatiss and Steven Moffat talked to Newsweek about the new season and the premiere episode's connection to Brexit.
"I've been writing this since last August. Thatcher is a natural substitute for Napoleon. [The story is based on Conan Doyle's 1904 Sherlock story The Adventures of the Six Napoleons.] We wanted to have fun with it and update it.
Steven, you recently criticized the government decision to reveal the salaries of BBC stars paid over £150,000. If, hypothetically, Cumberbatch and Freeman did not want their salaries on Sherlock revealed, would you take the show elsewhere, like Netflix?" Gattis said.
Moffat replied that he would never take the show away from BBC despite the stars getting better offers.
