The station's deadly mutant plant monster stowaway somehow gains control of Doctor Hilbert's mind, and it soon becomes clear that the crew has an emergency on their hands.
Minkowski insists on holding another of her infamous talent shows. Both Eiffel and Hilbert come up with schemes to weasel their way out of having to participate, but neither of their plans goes quite as expected.
Eiffel is surprised to discover a message waiting for him in the Communications Room. When the decoded message turns out to be a cryptic warning about something only identified as the "Empty Man".
An explosion puts a hole in one of the station's walls and uncovers a mysterious, concealed laboratory. As the crew explores the hidden room and uncovers data on its previous occupants, Eiffel is forced to confront one of his fears.
In a set of short stories, we get to see what the Hephaestus crew does when they are by themselves. Doctor Hilbert tells a joke and ponders a question. Hera plays a game. Eiffel takes a test. Minkowski sends a message.
It's Christmas Day, Minkowski does her best to approximate a traditional holiday dinner, Eiffel decides he's going to try to smoke his last cigarette. Both plans are put on hold, however, when Dr. Hilbert stumbles upon a major discovery.
The repercussions of the crew's discovery and Dr. Hilbert's actions continue to disrupt the station's Christmas plans. Cut off from Minkowski and with limited time to act, Eiffel decides to take a risk.
Unsure of who or what to trust after the events at Christmas, Eiffel and Minkowski make contact with Mr. Cutter, their liaison to Goddard Futuristics and the mission's direct supervisor.
Eiffel, Minkowski, and Hera are staving off boredom. Desperate to pass the time, the crew goes through games, contests, bets, jokes, minor intrigue, secret-telling, rare moments of sincerity, and even a bit of honest work.
An emergency leaves Eiffel and Minkowski stranded in the station's hidden laboratory. Their attempts to escape are put on hold, however, when they discover a hidden cache of audio logs left behind by Captain Lovelace.
The crew revisits the issue of how to handle Doctor Hilbert's continued presence on board. With Eiffel, Minkowski, and Hera all bringing their own perspectives, fears, and agendas to the table, discussions soon grind to a halt.
Eiffel decides to use Hilbert's mechanical skills to repair a faulty system in the station's optical network. Things seem to be going well, until Eiffel and Hilbert discover that one of their screwdrivers has vanished into thin air.
Minkowski makes it her mission to eliminate the mutant stowaway once and for all. But when her quarry proves surprisingly difficult to corner, the Commander resorts to increasingly desperate and dangerous tactics.
The crew is shocked by the sudden reappearance of Captain Lovelace. At first relieved to have another ally on board the Hephaestus, Eiffel, Minkowski, and Hera soon grow suspicious of the station's former commanding officer.
Eiffel, Minkowski, and Lovelace face technical difficulties, personal differences, and plummeting morale. But when a short circuit leaves them marooned outside the Hephaestus, they must race against the clock to repair the shuttle.
Eiffel and Hilbert try to find some middle ground as they adjust the Hephaestus systems. But with old grudges coming to a boil and Lovelace getting ever closer to her goals, will the volatile team be able to get the job done?
With Eiffel in critical condition, Minkowski, Hilbert, and Lovelace are forced to put their differences on hold. But it's not long before the uneasy truce is teetering on the brink of open violence.
With the station infrastructure taking heavy damage and multiple systems failing, Eiffel, Minkowski, and Hera must scramble to find a way out of the storm.
Eiffel, Minkowski, and Hera desperately work to get the Hephaestus back on a stable orbit, while Hilbert and Lovelace face their own time-sensitive challenge.
Colonel Kepler decides to run a comprehensive job review. Each faced with unique challenges, Eiffel, Minkowski, Lovelace, and Hilbert all struggle to prove their worth, preserve their autonomy, and stay ahead of the new management.
Eiffel and Hilbert run tests to determine the status of the virus inside the his body. The two men are forced to deal with an unexpected complication, however, when Colonel Kepler decides he wants to sit in on the proceedings.
Colonel Kepler puts everyone on high alert. Split into two teams and forced to stay up on an all-night stakeout, the crew must find ways to keep busy and face unique challenges.
As they struggle with a demanding schedule, an expanding workload, and Colonel Kepler's growing secrecy, tensions amongst the crew members - both old and new - are on the verge of a breaking point.
An accident leaves Dr. Maxwell in imminent danger and the entire station in a state of emergency. The crew scrambles to mount a rescue, but when Kepler and Minkowski disagree over which is the best way to conduct the operation.
When Jacobi repeatedly tries put an additional signal receiver in orbit. However, when they hit by an unexpected series of stellar flares, they might finally be able to get some hard data on the origin of the deep space signals.
