Murder on the Blade? examines the case against Scott Watson, convicted of the New Year's Eve 1997 murders of Ben Smart and Olivia Hope. Documentary producer Keith Hunter interviews witnesses and examines the evidence, arguing that Watson was wrongly convicted.  From the dvd description:  "The film visualises the central arguments and presents the views of the most vital prosecution eyewitnesses, who make it clear that they believe they were tricked into identifying Watson as the killer.  Their views are unanimously that Watson is innocent".

Along with the interviews, the film also includes brief recreations of key parts of the trial.  Michael plays one of Watson's defence lawyers in these segments.
