Even though this film was a flag waving gift to the British war effort, this did not take away from the interesting plot that was contained within the story. Two officers of the same war ship has been married to the same woman and she just so happens to be on a transport vessel that the Germans plan to sink. This is the rub of the story as now conflict between the two officers must be settled before engaging the Germans in a sea battle. And as you can guess from a 1940 British war movie, the allies are going to give their best as the brutes from central Europe try to advance on the people of Great Britain.
For a fast paced early war movie, this was played well by the actors. But for some reason, the filming studio decided, perhaps to save money, used a large amount of miniatures during most of the film which took away from the viewing pleasure. It was probably necessary to use miniatures for some of the fight scenes but this film went well overboard by filming all actors in a studio environment using a water tub for close-up scenes of ships. It was so obvious and useless that they even used studio tanks for lazy shots of a ship that was calm in the water.
Overall the film, even with its cheap looks, did entertain enough to make the story interesting to the end. A bit of help from the studio would have made this project much better.
