Captain Robert Daly and his Space Fleet crew embark on missions in their space ship, fighting their archenemy, Valdack. In the real world, Robert Daly is the Chief Technical Officer at Callister Inc. It's Nanette Cole's first day and she feels privileged to work under Daly. Walton gives her a tour of the office. At home, Daly goes into Space Fleet and abuses Walton and the crew.
The next day, Daly gets Nanette's DNA from a coffee cup and uploads her into Space Fleet. She finds herself and her coworkers digitally cloned into Infinity. Nanette quickly learns Daly is in control and they are transported to a planet where they meet Valdack and Jillian.
Jesse Plemons is great as the villain, weak in the real world and an all-powerful God in his created world. Cristin Milioti is excellent in her role as Nanette, who cleverly finds a way to break away from Daly's game. The rest of the crew is also very good, Jimmi Simpson (one of the McPoyles from It's Always Sunny) gives a dramatic and comical performance.
Director Toby Haynes makes this episode feel like a Star Trek journey with a Black Mirror twist. The special effects of space and the monsters are very well done. The lighting within the ship brightens when Daly is present and dims when he leaves, giving the sense of dread the prisoners feel.
USS Callister uses technology from earlier episodes like the cookies and turns it into a thrilling and dramatic space adventure. A strong start to Season 4.
9/10
