Rent The Beiderbecke Tapes (1987)

When Trevor (James Bolam)is offered some jazz tapes from the barman at the local pub - a fellow Bix Beiderbecke fan, he never dreamed that he would be receiving far more than music compilations! When one of the tapes turns out to be a clandestine recording of a sinister conversation about dumping nuclear waste in the Yorkshire Dales, environmentalist Jill (Barbara Flynn)is alarmed. Trevor and Jill return to the pub to confront the barman, only to find that he has gone missing. The two suddenly find themselves embroiled in a mystery, which follows them to Amsterdam and Edinburgh.
