As spring evenings lengthen over Kilnavarn House, two sisters, looking after their infirm mother, navigate the fragile territory between past and present. Memories of a troubled upbringing resurface and the house holds onto the women, as it always has, refusing to let them go until long suppressed truths are spoken. Sweep the Cobwebs off the Sky is a tender exploration of ageing, memory, place, and the desire for reconciliation.
