Edge of Madness began life as the short story A Wilderness
Station by acclaimed Canadian writer Alice Munro. It is
1853 and the action starts as a young woman stumbles into
the Fort Garry trading post. Almost half-mad after wandering
through the wilderness for several days, the 18-year-old
Annie claims to have murdered her husband, a 20-year-old
pioneer. The young man who passes for a constable in this
outback hamlet must try to determine who she is and what,
if any, truth resides in her story.
The actual story is revealed slowly, inside her flashbacks,
as he interrogates her. While locked up in the local
jail and under investigation, Annie gradually unravels
her story as she remembers it, trying to determine
her own role in what happened.
