"Merlusse" is French schoolboy slang for codfish, and M. Blanchard, a professor at a certain lycée, was known to his victims by that name. On Christmas Eve, when some twenty of the students—orphans, foreigners or just plain "unwanteds"—had to remain in the boarding school, Merlusse is placed in charge. His glass eye glares at them stonily, his good one with no less severity. He sets them to tasks, marches like a proctor up and down the aisles, exacts to the utmost the last measure of discipline. But when the youngsters awake in the morning, there are toys by each bed in the dormitory and M. Blanchard, no longer to be called Merlusse, is exposed for the softhearted fraud he is.
"Black Widow" has strong female characters but sidelines its title character and serves as a launchpad for her successor, Florence Pugh's Yelena.
A surprise sequel takes place ten years after the original movie based on the title of the same name, but with a twist to the fairy tale.
