Welcome to Grosvenor Arms, a 6-story-tall apartment full of eclectic residents that each hold pieces of a story of what happened to a missing couple who reside in the building.

Officer Walter Wolfe has arrived to Grosvenor Arms to conduct a welfare check on Jeffrey and Tamara Burmeister, a couple who live on the sixth floor of the building. It has been two days since anyone has heard from either two, and Wolfe is here to figure out why. But first, he must wait for the landlord to arrive with the key to open the door.

In the meantime, he makes his trek up the stairs, floor by floor, and interviewing each resident of the building:

Floor One: Miss Lily Berg, a short and stout, bubbly anatomy professor who had befriended Tamara shortly after Tamara had moved in. Lily helps Tamara with her lines as she earns her way toward becoming a successful actress, while also being someone to talk to about her problems with Jeffrey.
​
Floor Two: Monica Snyder, a retired model who has traveled the world to places not many people get to see. She uses her seductive looks to lure in unsuspecting men for casual encounters, and also holds intuition about Jeffrey that might ring a little too true.

Floor Three: A trio of Vietnamese brothers and their mother who own a family restaurant, while the brothers partake in gang-related activities. They had a heated confrontation with Jeffrey shortly before he’d been reported missing, while confessing that Tamara may have a serious illness.

Floor Four: Marky Mesquite, a gay computer technician that loves himself a Bloody Mary. He reveals that Jeffrey has questionable tendencies while Tamara may have an illness that’s more bizarre than anything else.

Floor Five: Twin brothers who have no social skills whatsoever. While living in a dump, they have the attention span of less than that of a goldfish, buzzing back and forth in neverending bickering, but provide bizarre details about Jeffrey and provide a clue about Tamara that makes the case more interesting than it already was.

Floor Six: The top unit apartment where the couple reside, locked and separating Wolfe from all the answers to his questions. What happened to Jeffrey and Tamara Burmeister?
