The Enterprise is docked at the Remmler Array where it set to undergo a "baryon sweep" a process where the ship is decontaminated of radioactive material accumulated during warp-travel. Things are hectic on the ship is everyone prepares for the decon, where there ship has to be vacant because the sweep is harmful to biological material, and to stay planet-side for the duration.
Once off the ship, Picard attends a small reception with the rest of the senior staff with the commander of the array when an off-handed comment is made about a local stable. Picard, excited over the idea of riding in what he feels to be ideal conditions to return to the ship to retrieve his saddle before the sweep begins.
Onboard and with minutes left to go, Picard encounters one of the array's workmen who confronts Picard, Picard makes an excuse for being there and tries to leave but the workman makes an aggressive approach towards Picard who's able to quickly react and take down the workman. He tries to transport off the ship but the ship shuts down just as the transporter warms up, trapping Picard on the ship.
Picard tries questioning the workman but doesn't get much info and soon finds himself captured by other stowaways and taken to Engineering. The group are batch of terrorists/mercenaries collecting a byproduct of the ship's engines, trilithium, that has potential use in weapons. They've set up a shield in engineering to protect themselves from "the sweep" but Picard is able to manage an escape and destroy the divertor.
After collecting some weapons from Worf's quarters (phasers can't operate due to presence of the sweep) Picard makes his way to Sickbay to begin improvising other means of defense. He overhears over a radio that the terrorists intend to transport the trilithium to Ten-Forward where they likely will be beamed off the ship. Picard tries to convince them, to no avail, to not transport the unstable compound through the ship and boasts that he'll be on their escape ship as well.
He manages to get himself recaptured by the two remaining members of the terrorist group as they head for Ten-Forward where Picard has, indeed, set-up a trap which manages to cause a distraction that gives him the advantage in a battle just as the sweep enters the room. One of the remaining terrorists is killed by the sweep and the other one manages to transport off by her ship.
Picard crawls into the structural supports of the Ten-Forward windows and calls for help to the array, which is shut-off just before it reaches Picard. When asked about the recent transport and nearby ship, Picard says that they won't get far as he removed a safety device from the canister. He watches as the escape ship explodes outside the Ten-Forward windows.
As all of this is happening, the rest of the senior staff (minus Worf who was able to get himself excused from the reception) inadvertently make the planet-side terrorists nervous enough to start their end of the plan too early. During a scuffle, Geordi is injured but Beverly is able to modify his VISOR in order to cause a distraction that incapacitates everyone in the room, allowing Data to figure out what is happening and to receive Picard's message and stop the sweep.
Reunited on the ship everyone is happy and safe and Picard is reunited with his saddle.

Die Hard on a starship.
Usually what I think of when it comes to this episode and it's the start of "battle-ass Picard" that we see more of in the movies. Here it mostly works as we see Picard handle himself quite well in hand-to-hand combat with the various terrorists and to improvise ways to make his escape and survival possible.
Kudos to the show for making the lead terrorists females and they're not stereotypical "female badguys" as we see the lead terrorist being fairly cold and indifferent to the deaths of her comrades through the episode.
Oddly, a touch out of character and out of 24th-century-humanity Picard is also fairly indifferent about the deaths he "causes" through the episode. Sure, he had no other choice but he seemed to to easily leave people behind where they'd surely be killed by the sweep. We get a brief moment of shock on him when the guy in the Jeffery's Tube is killed but that's about it.
Along with the "Die Hard on a.." trope Picard manages to get his hands on a communications device. Rather than this being like every other communications device we see in all of Trek where it's strictly person-to-person this one seems to operate closer to present day radio communications where someone can listen in on a channel, though apparently having two or three channel operation allowing for over-talking and for one to listen to a conversation while speaking/pressing the "talk" button.
An minor B-Plot deals with Data's most recent exploration in humanity is him doing "small talk" where he engages people in trivial, anecdotal, conversation to fills gaps in more important talk. He does to the annoyance of some of his co-workers but manages to take-off with it with Commander Hutchinson on the planet, a man who's said to be an expert at making small talk (and annoying others with it.) It's actually one of the few aspects of humanity we see Data try and emulate in the series that he actually seems to master quite well.
Unfortunately for "Hutch" he got a literal red-shirt kill in this episode.
It's lucky that Worf managed to excuse himself out of the reception as he likely would have made for a more formidable presence in the planet-side encounter. Fortunate for our heroes, but unfortunate for him, Geordi was not able to excuse him from the reception leading to him being shot but his VISOR plays an important role in saving the day.
I find it very hard to believe that at no point Picard could have stopped the ship's shutdown.
During the opening segment of the show we see everyone buzzing around and its implying the deboarding is taking longer than usual and is quite hectic. While setting up diverters for certain areas and such likely would slow things down, I would think a quick evacuation procedure from the ship would be a nailed-down plan. Hell, the ship was easily and quickly evacuated in minutes when they thought it was going to explode in 01101100.
But, it's a good episode. One that I can enjoy watching, it is nice seeing Picard in a more action-hero esque sort of position while alone on the ship.
And, well, you have to like the joke at the end.
Picard when talking about finding his saddle: "I only wish I got to use it on a horse."
Worf: "Of course."
