Mother and daughter Senga and Nat(Madeleine Stowe and Mischa Barton) are driving home and spend the whole journey picking at eachother and arguing the toss. Nat wants to go to a music festival, Senga is dead against it, Senga is weary of her life in general while Nat thinks her mother is just feeling sorry for herself. Apart from the fractious relationship with her daughter, Senga is popping pills, she keeps seeing the same group of people again and again, at the truck stop and at the side of the road. Even the evangelist on the television is talking directly to her. After a particulary bad arguement, Nat storms off. Senga witnesses her daughter getting into a mobile trailer with the very same group of people she keeps on bumping into. What follows is Senga's desperate attempts to find her missing daughter, a journey that makes her question her own sanity.
The ending to a film is very important. No matter what has gone on throughout a film, a satisfying conclusion is necessary to leave the viewer feeling totally happy with what they have witnessed. That is what is lacking with 'Octane'. For most of the film, a careful build up of tension is maintained, and the viewer is treated to quite a few nice set pieces along the way. The ending abandons all the atmosphere and subtlety in order to treat the viewer to a barnstorming ending. For me it ruined what could have been a minor classic.
There are many things to enjoy along the way though. Stowe's performance is excellent, the gatherings of the unknown people are pretty creepy affairs, there is a nice music score from British electronic duo Orbital and the film is great to look at. On the minus suide you have the lame duck ending, a panto villian performance from Jonathan Rhys Meyers and a couple of completely unnecessary twists in the plot.
Well worth watching once though. Who knows the ending might make the film for you. No extras on the disc by the way. 3 out of 5
