Beware My Brethren (Blu-ray) (Import)

Robert Hartford-Davis directs this 1970s sexploitation horror musical. The 'Christian Children Evangelical Crusade', aka The Brethren, is a religious cult led by The Minister (Patrick Magee). The fanatical Birdy Wemyss (Ann Todd) has dedicated her life to the Brethren, holding meetings in a chapel in her house. Her religious convictions have so warped the consciousness of her psychotic, sexually-frustrated son Kenny (Tony Beckley) that he eventually loses his mind and goes on a violent rampage, seeking his redemption in the murder and mutilation of prostitutes and any other women he deems morally corrupt.
