In Springmount, County Wexford, Will watches Kate Kelly through her cottage window—a moth at the glass. As the strains of a reel fill the air, Kate and her brother Philly begin to dance, while old Mrs. Kelly sits by the fire and looks on. Desperate to understand how the terrible tragedy of his past can so haunt his present, Will thinks back to the days of the 1920s. A meditation on love and the past, A Moth at the Glass is a lyrical evocation of a time when mountain lads roamed country lanes, loaded pistols in their pockets, and innocence and romance were corrupted by a passion that ran all too deep.
