Ils think it’s set in the future or at least on another planet (or galaxy…) and there’s à killer with a sword that cuts a specific part (nerve or tendon) so the victim can’t move and slowly falls to the ground but the killer puts the sword under them waiting for them to impale themselves.

And maybe there was this other guy having a relationship with a robot or hologram girl

It was on TV like 10 years ago or 15 maximum, it was in color

It was probably american

Been wondering if this wasn’t just a dream for a while so please help !
