Her voice is soft and plaintive, her words a slurry of apologies. For I Know My Weakness shows what happens when a woman who has been a homeless alcoholic for many years returns to the children she had abandoned. Unable to hide from her past, she is forced to contemplate her wounded life and its wake of wreckage. The film explores uncharted territories in the margins around us every day, in every city, in a 'direct cinema' documentary where the filmmaker himself is caught in the vortex of other people's nightmares.
