The team gets introduced to Robbie's painful rules of reality TV filming. The build team has been working together for years and is eager to get started. Room ideas are revealed while rooms of yesteryear get torn down. Cetti is forced to clean out the remains of a few thousand cockroaches that were used in last year's haunt.

The team starts a new room, "Showers", which requires Eduardo and Carlos to go on a necessary but satirical tile shopping trip. The new reality of being filmed for a reality show causes team turmoil and 2 members quit. A workplace injury has Robbie reassessing his treatment of his crew.

Robbie forgets his anniversary but brushes it aside to start the build on a 3rd room, "Circle Shocks". While the team kicks ass on building 3 rooms simultaneously, Lane reveals his lack of skill and confidence while fabricating shock chairs. Wyatt and Robbie grind through the night to prepare for a big event, cast auditions.

Heather takes the reins of her cast management team to coordinate auditions. A break from the grind of a haunt build, auditions day is filled with goofballs, pranks, and some questionably low standards for who might become a scare "actor" for The 17th Door.

The team starts and makes fast progress on the build of their spinning room, "Tumbler". Serious questions about the safety of a room that spins upside down are answered during an intense test session with the entire team. Cetti receives mean jokes and backlash from Robbie over a harmless build design suggestion.

Robbie convinces his brother, Jamie, to come help film this year's cinematic trailer for the haunt. Jamie's disapproval of the haunt's content and reluctance to be on a reality show contribute to an already explosive brother dynamic. The team starts building the suffocation room entitled "Breathless". Heather takes one for the team and eats cow brains.

The workload increases with cast training and Heather struggles to balance work, raising her 3 boys, and her marriage. Robbie has been sleeping at the haunt to increase productivity, but this puts even more strain on their relationship. With time till opening night running out, the team takes a strangely necessary but comedic detour to collect honey from some invasive bees.

Dress rehearsal is a total flop as 4 of the 17 rooms still aren't finished and 1 of them hasn't even been started. With opening night only 48 hours away, some of the team confront Robbie about making hard decisions to scale back some of the rooms to avoid an opening night embarrassment.

It's opening night. Friends and family of the team join an all day push to get the haunt ready before guests arrive. The build team frantically works to get all 17 rooms ready while Robbie troubleshoots numerous technical difficulties. Cast energy and optimism are extremely high as some will be scaring for the first time.

The pressure is on for Heather to step up and lead the operation towards Robbie's lofty attendance goals. To help ticket sales, Robbie finally completes and releases the new VR experience. Heather struggles with her most fragile cast member, "Mr. Glass".

Robbie allows 2 super fans to get married at the haunt, as long as he can be the wedding planner. Heather deals with a range of annoying cast problems including a male to male bitch slap and the ego of a haunter going through a midlife crisis. Scientists from Caltech perform a study about fear while being annoyed by reality cameramen and fake homeless guys.

The team celebrates Heather's 40th birthday as the nights grow busier and the guests get rowdier. Heather's patience wears thin as one of the cast members has an overly dramatic and very public "panic attack" that some find hard to believe.

Heather pushes to hit the season attendance goal during the last few nights of operations. The cast is motivated to finish strong, but saddened by the goodbyes that will soon follow. On a lighter note, Heather and Robbie go scaring together while guests punch each other in the face.
