Helluva Boss

The enthusiastic imp Blitzo and his subordinate employees—Moxxie, Millie (Moxxie's wife), and Loona (Blitzo's adopted daughter and the I.M.P. receptionist)—run an assassination agency called the Immediate Murder Professionals (I.M.P.). Some backstory is provided, as shown in a flashback, when Blitzo steals a book used to make a portal to the living world from Stolas, one of the Goetial demons of Hell after having sex with him, and when the group is shown accidentally shooting a small child named Eddie while aiming for someone else. The group later kills and disembowels Eddie after discovering he was the right target their client wanted them to kill after all, and drops off his dismembered body in a bag to his mother on live TV.

An affable school-teacher named Mrs. Mayberry (Mara Wilson) video calls her husband on his birthday, only to realize that her husband has been cheating on her with another woman named Martha (Jinkx Monsoon). In a fit of explosive rage, she attacks Martha and kills her husband with a chainsaw and shotgun, before committing suicide after realizing what she has done—all to the shock of her class, who witness this via the still-on video chat. However, it's revealed that Martha survived and became a filthy-rich woman who is praised as a "hero" for surviving the attack. Mrs. Mayberry, now a sinner/demon living in the Pride Ring, hires I.M.P. to take Martha out. During the first attempt on the assassination, Moxxie's hesitation to kill a mother and ruin a seemingly innocent family deliberately causes Blitzo to miss his shot, alerting Martha and her family, who then reveal their true, villainous nature and proceed to chase them. Blitzo and Millie flee, but Moxxie is captured by the children. Millie attempts to kill Ralphie (Maxwell Atoms), Martha's husband, only to be knocked out.

Meanwhile, as he's running for his life from a shotgun-wielding Martha, Blitzo (who's shot) receives a call from Stolas (Bryce Pinkham), and after hastily talking, Blitzo gets captured by Martha. Moxxie finds out the family are murderous, gun-wielding cannibals when he wakes up, tied to a chair in a room adorned with dead people and animals. He escapes, fatally shoots Martha from behind, and rescues Blitzo and Millie, just as they're about to be shot (after being burned at the stake didn't work). Moxxie stays behind longer than the others in order to kill Ralphie and the kids as well. However, despite calling them monsters, he decides not to kill them and that they should still have a chance at a life and a purpose, so he calls the local authorities to deal with them and have them answer for their crimes. Right before he heads back through the portal to Hell, the police (who've surrounded the house) instead blow up the family along with their house. Moxxie witnesses all of this before being dragged back by Blitzo. Back in Hell, Blitzo, Millie, Loona, and Mrs. Mayberry celebrate over a cake, while a traumatized Moxxie sits in complete shock, trying to comprehend that he caused a whole family's death.

A cry in the night awakens Stolas. After a brief exchange with his wife, he goes to check on their daughter, Octavia (nicknamed Via). Octavia had just had a nightmare, so her father sings her a lullaby of reassurance. Years later, Octavia (Barrett Wilbert Weed) wakes up from hearing the yelling of her mother, Stella (Georgina Leahy). After finding out about Stolas's affair with Blitzo the imp (the lowest class of demon), the classist Stella is enraged about Stolas besmirching the prestige of the Goetial family. Octavia goes to eat breakfast while her mother leaves the kitchen in disgust. Wanting to get out of the house and away from his wife, Stolas decides to take Octavia to Loo Loo Land, an amusement park that she enjoyed as a kid, and he hires I.M.P. (with the exception of Loona) serving as their bodyguards.

During the day, Stolas takes Octavia to watch the show of circus performer Robo Fizz (Alex Brightman), who both Octavia and Blitzo hate due to personal reasons. Octavia runs away from the show, and Stolas follows her to the funhouse ride, where they talk about how things have changed. Octavia is upset that her home doesn't feel like home anymore. Stolas tries to explain his relationship with his wife but can't find the right words to say. Octavia expresses that she feels Stolas will leave her behind in favor of Blitzo, and Stolas assures her that that would never happen. Meanwhile, Blitzo gets into a fight with Robo Fizz that ultimately causes Loo Loo Land to burn to the ground. An exhausted and injured Blitzo, Moxxie, and Millie leave with Stolas and Octavia as the episode wraps up.

In order to get their company's parking space back from his pop-star ex, Verosika Mayday (Cristina Vee), Blitzo and the rest of I.M.P. challenge her and her posse of succubi to a challenge; I.M.P. could kill more people than Verosika and fiends could have sex with. With partying spring-breakers as targets, Loona disguises herself as an attractive human goth girl and lures victims to obscure spots for the rest of her team to kill them. However, she catches feelings for Verosika's Hellhound, Vortex (James Monroe Iglehart) and stops helping I.M.P. in favor of talking to him. Blitzo becomes upset about Loona's crush on Vortex and tries to intervene, only for Loona to yell at Blitzo and tell him to stop treating her like a child and let her make her own choices. Blitzo becomes upset and storms off, abandoning the challenge as well. Meanwhile, Verosika sings on a stage, and uses her siren-like voice to turn the humans into sexual deviants, which her team subsequently seduces. Moxxie and Millie take the challenge into their own hands and continue killing people, but some humans catch Moxxie and throw him into a beer barrel, which makes him drunk. As Millie rescues Moxxie from the barrel, a fish mutated by a beer can Verosika threw into the water starts attacking the beach, scaring away the humans. Millie kills the monster, and Blitzo uses the incident to blackmail Verosika into giving I.M.P. their parking space back.The episode ends with Blitzo and the others returning to Hell to reclaim their parking space once again, while Verosika and her team are arrested by the human police because of the chaos they caused on the beach.
