May I have some help looking for a story title?

Hey guys I’m just wondering if I could get some help for this episode story that I read back in 2015 or 2016 ish. It’s quite an old story so I don’t know how much luck I’ve got.
The plot talks about the main character travelling to Mexico on a trip (I think like graduation travel or something), and it is in Mexico where she gets roped into human tr*fficking…and it kinda just talks about her story and trying to escape I think?
Thanks in advance!
