'Harry Duggan is a fisherman—an easy-going, pleasant chap—who has married Mag, a woman who had a son by a previous relationship. The life of Harry and Mag is wholesome and smooth, until suddenly Charlie, the grown-up “bad penny” son, turns up. The ensuing scenes round the waterfront have in them the growing interest of an intolerable triangular situation.'
