Hillwalkers is mind-bendingly terrible. I won't describe the plot because there is no plot. If you want something inherently bad, watch this absolute mess. It does not even qualify as "so bad its good". This is genuinely one of the worst things I have ever seen.
Do yourself a favour, avoid this because you do not deserve to have this much of your life wasted.
It's not just bad, it's eye-wateringly awful. There are scenes in this that Tommy Wiseau, who made 'the Room', would have said, ''I'm sorry, that's actually not up to snuff - we're going to have to take that out.' This is not cinema; this is something so staggeringly self-regarding."
FYI, 'the Room' is widely considered to be one of the worst films of all time. Hillwalkers makes 'the Room' look like 'Citizen Kane'!.
There was clearly no direction given to the actors, as the performances... well, the very bad performances, are in a stratosphere of their own. Hillwalkers is not even worth seeing for a laugh.
The director should probably find a new hobby, gardening perhaps? But if the same lack of skill is applied to that endevour, God help us all...
