WARNING: If you don't want to know what happens in this episode, don't read this photo recap!
A woman we will come to know as Julie Mao floats in tight quarters in zero gravity, barely quenching her thirst with literally her last two drops of water. She cries for help, but no help's coming.
195549
Julie manages to break free of the room, donning a space suit and magnetic boots to explore what looks like an abandoned spaceship. She notices blood on the airlock door ... and an S.O.S. signal coming from the Engineering Bay.
195550
Julie enters the Engineering Bay ... and steps into a nightmare. She screams at this ghoulish sight.
195551
At Ceres Station, an asteroid that's been transformed into the most vital port in 'The Belt,' a street preacher rails against the slave-like conditions of the Belters who work the docks, living in a world where their air and water are rationed … and warns of an impending war between Mars and Earth, with Ceres caught in the middle.
195552
Detective Joe Miller, a hard-boiled, hard-drinking, hat-wearing detective for Star Helix Security, is showing a new recuit, Detective Dmitri Havelock, around Ceres. Havelock is struck by the appearance of 'Belters,' who have spindly fingers and long limbs due to years of living in "low-G."
195553
At the local brothel, Miller comforts a prostitute, Gia, whose latest john, a Belter gangster, has just been whacked by unknown assailants.
195554
Back at Star Helix Headquarters, Captain Shaddid gives Miller his latest assignment: find Julie Mao, the rich heiress to Mao-Kwikowski Mercantile and the black sheep daughter of Ariadne and Jules-Pierre Mao. Julie, of course, is the woman we saw at the beginning of the episode.
195555
Miller asks his ex-lover and fellow cop, Octavia Muss, for a "woman's intuition" regarding Julie's case. Julie defied her parents by becoming a member of a student protest movement known as the Far Horizons Foundation … and the champion pilot of a racing ship known as the Razorback. Where could she have gone?
195556
Witnessing children suffer at the local sweatshop due to the poor air filtration system makes Miller think twice about being on the take with the sweatshop's proprietor, Vargas. Miller throws Vargas into the airlock and lets him gasp just long enough to make his point.
195557
Meanwhile, on Earth, we meet Chrisjen Avasarala, the U.N. Deputy Undersecretary, who's enjoying an idyllic day with her husband Arjun Rao and young grandson in her Westchester home.
195558
That is, until U.N. officials transport her to a black site, where they're questioning Heikki Sobong, a member of the rabble-rousing Outer Planets Alliance (OPA) accused of carrying contraband stealth technology. The OPA is a unauthorized political organization fighting for The Asteroid Belt to be its own government. Being a Belter, Sobong's fragile bones and lungs are crushed by Earth's gravity -- simple and effective torture, though he's not talking.
195559
Meanwhile, in outer space, the ice trawler Canterbury is about to deliver a shipment to Ceres Station when the crew receives a distress signal. As an investigation would mean a late arrival and therefore losing their on-time bonuses, Captain McDowell opts to purge the message as if they never received it.
195560
This decision doesn't sit right with Second Officer James Holden, whom the Captain has been courting to be the ship's new XO upon the old one going crazy. Holden's usually content to have as little responsibility as possible as he romances the ship's navigator Ade Nygaard in zero gravity, but something about that transmission bothers him ...
195561
… especially when he enhances it to reveal a woman's voice saying "Please help me." Holden secretly logs the message with HQ, which means the Canterbury is now obliged to investigate.
195562
After performing a painful, high-G "flip and burn," the Canterbury approaches a wounded ship in the dead of space: the Scopuli, a name we saw on Julie Mao's space suit in the very first scene.
195563
Holden, engineer Naomi Nagata, mechanic Amos Burton, med-tech officer Shed Garvey and pilot Alex Kamal take the Canterbury's shuttle, the Knight, to get a closer look at the derelict spacecraft.
195564
On board the Scopuli, they find the source of the distress signal, and no trace of survivors ...
195565
... and hightail it out of there once they receive word from the Canterbury that an unidentified ship has entered their vicinity.
195566
The mystery ship -- which Alex theorizes is Martian due to its stealth tech -- fires torpedoes, which sail past the Knight and head straight for the Canterbury. Holden's lover Ade gives one last transmission: "There's something you should know …," before the Canterbury — and everyone on board — is blown to kingdom come!
