June 11 (UPI) -- Season 6 of the British spy thriller, Slow Horses, will premiere on Apple TV Sept. 16.

A short teaser released on Thursday showed J.K. Coe (Tom Brooke) beating up an intruder at Slough House.

His boss Jackson Lamb (Gary Oldman) then enters, asking, "Who the [expletive] is that?" as colleague Roddy Ho (Christopher Chung) looks on.

Co-starring Kristin Scott Thomas, Jack Lowden and Hugo Weaving, the show focuses on Lamb and his fellow MI-5 outcasts, who work cases from a remote, run-down location.
