Non Compos Mentis (Not of Sound Mind) is the chilling story of disturbed office worker Rob (Chris Brooklyn) who lives alone in semi-darkness in a house he has insulated against the realities of the outside world by covering all the windows in newspaper. Unable to form a relationship on a 'normal' level, Rob instead inhabits a fantasy world of his own creation, fuelled by his isolation and prodigious appetite for pornography. Things become a little more 'real' for Rob when he meets Michelle (Biba Lille West), the girl of his dreams. However, all is not as it seems, and the dream becomes a nightmare when Michelle turns out to be the catalyst that sends Rob on a downward spiral of lust, murder and extreme sexual deviance.
