I don't know if this was ever shown in theatres but it has a 'straight to video' feel to it. Two friends are invited to a brothel for a night of debauchery. How this happened is glossed over, although there is a plot twist that doesn't really work because of it. Acting across the board is wooden, and dialogue often echoes as if filmed in a studio without sound deadening.
An introductory scene is referred to later in the story, but was probably unnecessary. A character who plays little part in the first half of the film is introduced as a surprise, but most will have worked out his role early on. The script is likely to offend many; the two non-white characters (one 'good', one evil) are not sympathetic roles. There is glorification of indiscriminate drug use, and misogynist language. Some elements of the story bear so little connection to the plot that they were possibly used purely to increase the gore.
I suspect my attention drifted at times as I found myself wondering how we reached this point, but rewinding didn't clarify anything. Some will enjoy the Grand Guignol blood and guts, but more will likely find it cheap and tawdry. I am among the latter.
