What happens when a "drunk" woman asks for help finding her friends on a busy street in a major city?
Some pretty disturbing things, according to a Youtube video posted by a Spanish rehab clinic.
The "social experiment" shown in the clip has an actress pretend to drink alcohol alone in public areas in Madrid, Spain. She's shown in broad daylight appearing intoxicated and friendly as she drinks from a bottle in a bag.
The nearly 11-minute hidden-camera vid is in Spanish with English subtitles, and shows a series of men, whose faces are blurred out, approaching the actress. Some urge her to join them and drink more alcohol. One tries to usher her to a stairwell.
Yet another man tries to convince her to come to his hotel, saying she can charge her phone there.
In several encounters, the men touch the woman, sometimes taking her by the arm or putting their arms around her as they try to lead her away from the area. One man says, "Give me a hug!" and proceeds to do so.
But the most unsettling part of the video unfolds about seven minutes in.
At that point, a man takes her down a side street and tries to kiss her repeatedly. A crew member then intervenes, to which the man says, "Hey, why do you take her away? You don't take her!" according to the subtitles.
The clinic's director, Dr. Jose Miguel Gaona, explains in the video that similar experiments had been carried out elsewhere, in places like Los Angeles – although the alleged harassers in that video turned out to be actors themselves, and the video was dismissed as a hoax.
Gaona says that if situations like these can unfold when it's light out, then "What happens on a Thursday or Friday night when a teenager gets drunk?"
"The most disappointing fact is that we had no need to edit the video and avoid any scene of someone approaching to help this woman in such a delicate situation," he says.
"Why? Because nobody got close to help this drunken woman that was in the need of, maybe, get a taxi or help her in any other way."
Gaona says that, rather, the worst situations that showed physical abuse were the ones edited out, because there was no need to show it in such detail.
The video, which was produced by the clinic in conjunction with Doctortest.us, a site that sells at home drug-testing kits, is apparently the first of a series of social experiments the clinic will conduct in subsequent videos. The clinic's previous videos focus largely on the therapies offered by the clinic.
The video has many viewers outraged, with one commenter on Youtube saying: "That's quite scary. Also worried about many of the comments here [below the video]. 'Behaving like a slut.' It doesn't matter what anyone is behaving like, if they are very clearly drunk, you can't try to do what those guys did."
Last year, anti-harassment group Hollaback released a video that showed a woman being catcalled as she walked around New York City alone for 10 hours.
That video led to discussion around street harassment, and what can be done to prevent it, but also drew criticism for editing out examples of white men, and showing only men of colour catcalling the subject of the video.
Hollaback later issued a statement regretting its "unintended racial bias."
