1851, Manitoba's Red River Valley. As winter sets in, a young woman on the edge of madness arrives exhausted at the fort, a wilderness station, claiming she murdered her husband. She's placed in a cell; for the next several months, she sews while the local prefect, Henry Mullen, investigates.
Unfortunately the movie Edge of Madness is not yet available on HBO Max.
