Gilbert Renton is the owner and operator of a neglected, old hotel in the middle of crime-ridden Hell's Kitchen.
Although actually the "Hilton Hotel", the building is often referred to as the 'Ton by its residents and locals, because the first three letters on the sign are burned out. The building is inhabited by a myriad of undesirable occupants; junkies, criminals and vermin pass through the 'Ton on a regular basis, and not all are welcomed openly by Gilbert. Paul Denton, JC Denton's older brother, is a permanent resident of the 'Ton and one of Gil's favored tenants. Due to its poor location and declining rate of business, the 'Ton Hotel does not have any official employees, instead Gil's daughter, Sandra, is charged with maintaining the crumbling building alone whilst her father attends the desk, much to her chagrin.
Becoming increasingly tired and fed-up with her situation, Sandra abandons her father and the 'Ton, choosing to sell herself on the streets as one of JoJo Fine's many poorly treated prostitutes. Sandra's reckless decisions and precarious situation have left Gilbert an emotional and psychological wreck, as he constantly fears for her safety and pleads with her at every turn to stay well clear of JoJo and his thugs. In an act of desperation, Gil offered his daughter a well-paid position attending the 'Ton's desk, which she emphatically declined.
Although not a politically active individual, Gilbert's perception of the NSF is severely skewed when he finds himself and his beloved 'Ton Hotel in the middle of a hostage crisis brought about by a handful of desperate NSF troopers intent on slowing UNATCO's advance at all costs. At a later period, the 'Ton Hotel is once again forcefully occupied, this time by Sandra's former employer, JoJo Fine.
Determined not to allow his daughter and the 'Ton to become the property of a lowlife criminal such as JoJo, Gilbert plots to take matters into his own hands. There are many alternative ways in which Gilbert's story can play out, generally depending on Sandra and Gil's decisions and/or status after interaction with the player at a previous point in the game. The 'Tons fate is eventually sealed when a UNATCO incursion force, by order of Majestic 12, attempts to eliminate the Denton brothers in a raid on Paul's apartment. The subsequent firefight involving heavy smallarms and explosives encompasses the entire 'Ton Hotel, leaving the building badly damaged and unsafe for its remaining occupants. Gilbert is forced to have the building condemned, mentioning a new start somewhere far from New York City.
