On a return flight to the moon, Devis and Kenzy are rudely awakened by Spring’s latest hi-tech cop gadget: A phone. On the moon, Alexi is introducing the Safety Controller, Wolfhardt to Spring, just as the fancy space communicator blows up, much to Wolfhardt’s disdain.

Elsewhere, engineer Hooper is being a right asshole to his assistant, Anderson. He doesn’t like her, he doesn’t respect her and he shouts at her a lot. She puts in for a transfer, which Alexi denies. He suggests that she try again. Hooper is under a lot of stress.

Alexi also introduces Spring to his latest great idea. He’s asked a psychiatrist to come to the moon and interview everyone. He wants his command staff and the Star Cops to all mandatorily volunteer as a show of solidarity and confidence in the importance of the interviews with everyone on the base. Spring agrees.

Spring contacts David and forces him into a game of bridge. Wolfhardt apparently plays and Alexi is trying to smooth over his visit. That doesn’t go so well then the bridge table explodes on them during the game.

Back in the service corridors, Hoopers threatens Anderson with a projectile tool and she’s had enough. The Star Cops are called in and Hooper is just as unpleasant to them, but he also indicates that there’s a saboteur on the base. Which is the sort of thing you’d expect the chief engineer to have reported previously rather than just continue to be overworked having to fix everything. Spring assigns David, a qualified engineer, to help Hooper and to snoop around.

Upon returning to the moon, Kenzy learns of the mandatory voluntary psychiatric interviews and she goes into a strop. “I am NOT being analyzed!”

Devis, when he learns that Dr. Parr is coming runs and hides.

Spring picks up Dr. Parr and she’s immediately an obnoxious person, not at all the type person a patient would be comfortable talking with. She tries to ply Spring with her analytic jujitsu but does little more than provoke him.

Hooper tells David that the card table was wrongly wired, it looks like there really might be some sabotage.

The interviews begin with Anna Shoun, but it doesn’t last long when Dr. Parr learns that Colin Devis is one of the Star Cops on the base. She seems distracted and disturbed.

In the service corridors, David finds his own evidence of sabotage, a device keyed to his voice print. He takes his suspicions to Spring, but there is no proof Hooper was behind it.

Alexi and Wolfhardt, apparently old friends, have a heart-to-heart about the problems on the base. Then they take a moon buggy out to watch the Earth and drink vodka. They open up a bit to one another.

The next day, Parr reveals to Alexi that Wolfhardt divulged some of the things they’d spoken about. He is upset by this, and goes to look for Wolfhardt.

David was supposed to meet Hooper, but he’s not at the designated spot, and David suspects he was sent there so Hooper could avoid him. We see a saboteur in maintenance workers’ overalls and carrying Hooper’s toolbox tampering with things in the service corridors.

Kenzy still avoids her appointment with Parr, so Devis goes in her place. Dr. Parr is one of Devis’ ex-wives, and there’s still that joyous spark of antagonism between them, which does not stop Devis from trying to jump her bones. She rejects his advances.

We see the saboteur and it is Wolfhardt, who accidentally causes and explosion and decompression of the base. Anna and Alexi are trapped in the mess hall with several others, Spring and Kenzy are trapped in a small closet and Devis and Parr are trapped in Alexi’s office.

David, Hooper and Anderson, who steps up in the emergency, must don space suits and fix the damage before the people aboard the base die of asphyxiation.

Strangely, the service corridors have not lost air pressure and Wolfhardt is injured but not suffering from lack of air.

Trapped and facing death, Spring opens up to Kenzy and explains about how his father was a criminal and that he brought him to justice.

In Alexi’s office, after much prompting, Devis and Parr get down to having sex before they die.

When the base seals are repaired, the only way to get air to the survivors is to use the air in the service corridors and open all the internal doors manually. With everyone breathing again, Spring realizes that Wolfhardt must be the saboteur and was in the service corridors. They rescue him. Cracked, he didn’t even realize what he was doing.

Parr departs, his mission unsuccessful, but leaving Devis with a smile.

The End
