Night Boat to Dublin

During World War II, British intelligence officers embark on a perilous mission to track down a German spy suspected of passing atomic bomb secrets to Nazi Germany through the Irish Free State. Two undercover agents, Captain Grant and Captain Wilson, pose as ordinary passengers on an overnight ferry to Dublin, where they infiltrate the social circle of a suspect lawyer named Paul Faber. Their cat-and-mouse game leads them from London to a seaside mansion in Devon, culminating in a heart-pounding showdown with the German spy and his accomplices.
