No, this isn't about the Costner/Houston movie, or the Reynolds/Jackson train wreck..
Bodyguard is a six-episode 2018 BBC miniseries on Netflix. I just finished watching it and I thought it was pretty good. It's about the British equivalent to a Secret Service Protection Detail to their Home Secretary, I think that would be a Homeland Security Cabinet person here. The PPO is an Afghanistan Vet who has his doubts about who he's protecting and gets his head into places it shouldn't have been.
There is a plot against his protectee, and he is trying to get to the bottom of it. Somewhat, but not overly convoluted. A good point is you never quite know where all of the players stand.
The downsides is the amount of video surveillance the average Briton is subject to. That gives me the willies. They are also extremely pedantic when it comes to when the police give commands. The EOD guy took like three minutes (I exaggerate, but only slightly) to tell the person with the suicide vest how to turn around.
I enjoyed it, with Richard Madden of Game of Thrones fame (Robb Stark) playing the lead. I laughed when his wife climbing up and down walls for him like some l33t parkour. The finale in the U.K. is now the the most-watched episode of any drama since records began in 2002, according to the BBC.
