It begins with the crew of The Rocinante arriving on Martian-occupied Ganymede station and starting their search for Mei Meng and Dr. Strickland.
As Amos Burton and Prax Meng hunt for answers, Prax begins to realize there is a serious problem with the Station's air-recycling system.
Like the man-sized Bed Bug problem that killed all those Marines wasn't enough reason to sell your condo on Ganymede.
The Rocinante crews' search ultimately leads to a "man" named Roma—a sleazy, young opportunist, who trades his access to the station video records for food and supplies.
When he proves difficult to barter with, Amos responds appropriately, striking the man repeatedly in the head with a Spam-like can of chicken. Roma agrees, at gun-point, to help find young Mei and her Dr. Strickland free-of-charge.
While the station video records are being searched, Prax takes a deeper look at the air-cleaning system currently running on Ganymede.
As a botanist, he concludes the hydroponic-based oxygen recycling method will experience a cascade failure before long.
The search of surveillance network finally results in video footage of Dr. Strickland and a female with Prax’s daughter Mei safely leaving the recorded area of the station.
Back on The The Rocinante, Alex Kamal’s super-fun zero-gravity drinking game is interrupted by notification that the space around Ganymede Station is being closed by Martian authorities.
On Earth, the UNC and Martian delegates finalize the terms of the peace accord without further testimony from Sgt. Bobbie Draper.
Bobbie is reprimanded by Captain Martens for her revelations during earlier testimony. After being told she will be confined to the embassy until her departure, Draper decides to look for a way to break open the secure windows of her room.
Sadavir Errinwright calls for a deeper study of Sgt. Draper’s Body Armor, previously turned over to Earth by Mars.
Knowing the proto-molecule work by Jules-Pierre Mao as he does, he tasks the scientists to search for “exotic” biological traces.
Errinwright and Undersecretary meet to discuss Sgt. Draper’s encountered on Ganymede. He informs her of his belief that Ganymede was the result of weapons-testing by Mao for Mars, based on the same technology that wiped out the population of Eros.
He admits to colluding with Mao to weaponize the extra-solar “proto-molecule,” first discovered on the Martian moon Phobos.
After no small amount of trouble opening the window, Bobbie manages to get herself outside but is still four floors off the ground. Getting to Earth from there involves what I assume is a bad day for any student of Parkour. But she gets right up an makes a run for it!
In search of the Ocean, Sergeant Draper must adjust to the Earth environment and experiences life on Earth among the majority underclass.
Bobbie’s escape from the Martian Embassy draws the attention of Earther spy Cotyar (Nick Tarabay), who reports it to Undersecretary Avasarala.
The Sergeant finally fulfills her dream of seeing an ocean for the first time. While enjoying the moment, she is approached by Cotyar and the Undersecretary.
They show her evidence—a file entitled “Project Caliban – Protomolecule Phase 4 Hybrid” that depicts the creature Draper fought.
But convincing her isn’t going to be that easy—the Sergeant is not ready to accept the deaths of her squad, and the subsequent destruction of three domes on Ganymede, were the results of Martian weapons testing.
