Patric Knowles is engaged to Mabel Poulton, who leaves him and absconds with the as-yet-paid-for ring. This leaves Knowles indebted to unpleasant money lender Morris Harvey, who is not inclined to be forgiving. Knowles shows up at Harvey's shop only to find him murdered and encounters Beatrix Thomson fleeing the scene. He soon discovers that Thomson is his employer's (Frederick Piper) wife, and she tries to involve him in a scheme to kill him.
This is essentially a low budget quota quickie made by Teddington Studios, a British studio bought by Warner Brothers to produce British B films to pair with their A films in Britain. Despite being an obviously low budget outing, there are a few things of interest.
The main point of interest is that it's an early directorial outing for Michael Powell, although truth be told, besides being competently assembled, it doesn't bear much of his stamp. Thomson clearly dominates the film, and it's a welcome shift when she becomes the focus in the second half. It's also worth noting that even though the film bears the Warner Brothers logo, it was never intended to play outside of Britain, so it has more that a few elements that don't comply with the Production Code.
