Plot

...made to educate and warn Canadian troops about the dangers of catching venereal disease. As the biblical title suggests, it is essentially a straight sermon, a form that its target audience would have found familiar both from church at home and during their military service. The protagonist is warned, is tempted to ignore the advice, is rescued in the nick of time by a well-wisher and is finally shown the devastating consequences in another that he has so narrowly avoided.
