This film is kind of a study on public cruising and the dangers of it .... somewhat. Albeit, the story of the movie could be with any group of people ~ not necessarily the LGBTQ community ~ but with anyone who uses trails for whatever they use them for. A reviewer mentioned that it is sad that gay men seek those avenues for sexual fulfillment. Well, first, cruising and out door cruising ~ bathroom cruising (check out the film CAUGT on here ~ it's all about that, its consequences - the type of men doing it, etc. It's an amazing film) is as old as time itself. Second, it's not just gay men doing it, straight people cruise in public places, have out door sex just like gay people ... they're just not persecuted or targeted for it (not in the same sense as gays). Generally though, law enforcement has cracked down a lot on cruising and sex on trails and in parks and public places like that - albeit that kind of thing still goes on - it's not as prevalent as it was - say 25 years ago or before.
I don't want to be a spoiler, but someone said that the story line is a little preposterous. Well, not really. People go missing all the time ~ especially children - and with the explosion of online predators and sex trafficking, I don't think the story line is that preposterous - maybe a little over the top - but not preposterous. In fact, where I live right now, there have been reports on the news of young men - millennials - gone missing. Sometimes the bodies are found, sometimes not. Law enforcement thinks it's a serial killer targeting young gay men. Across the country. Not just here.
I do have my opinion on the ending, and I do question it. I'll probably have to watch it again to see if I'm interpreting the ending correctly.
