 A film about frustrated filmmaker Barry Licks attempts to make a documentary about a businessman, who he believes is involved in property rackets, prostitution, pornography, and the importation of recreational drugs. For security reasons Barry never uses his real name, and calls him Ray Topham. Barry recruits a team of young wannabees. Their quest leads them to two of Rays associates; a local cocaine supplier and ex-S&M porn actress called Joanne Miller, and the charmingly psychopathic Tommy Morghen who acts as Rays personal security consultant. They soon realise that Barry is out of his depth, and so they exploit him for their own purposes with both hilarious and tragic results. Diary of a Bad Lad explores themes of sex, drugs, violence, exploitation, and the desperate limits that people will go to in order to make a film.
