We drop in the middle of a roadtrip. The young couple Alex and Scarlett are driving through vast landscapes heading for LA. They stop at some little town to spend the night and from then on things get weird.
Scarlett becomes obsessed with a TV-preacher and later suffers ache which grows the further they get from the town. Then she disappears and Alex sets out to find her.
The film vaguely reminds of “Lost Highway“. It may be not that dark and weird, but story-wise there are similarities. That is about what you need to know. The atmosphere of “Bottom” is mostly drama, with some thriller elements and Alex going mad.
Judging the 5.3 IMdB rating, not everybody likes the film. It may not be a masterpiece, but I found it quite alright.
