Sins of the Mother: A young man returns home to Gloucester, Massachusetts, to investigate the mysterious death of his mother, a decade earlier. His return causes buried secrets to be unearthed, giving birth to murderous events and new secrets. Set in the rough and tumble world of Gloucester's waterfront and lumpers (dock-workers), Sins Of The Mother is Israel Horovitz's first full-length Gloucester-based play in a decade.
