Arthur Groom werkt in Londen terwijl zijn familie in Richmond woont. Kort na een ontmoeting met een meisje uit de showbusiness, wordt zij vermoord gevonden en wordt Groom aangewezen als mogelijke dader. Alle beschuldigende factoren wijzen naar de naïeve Groom, die te laat ontdekt dat hij in een wespennest terecht gekomen is.
Nee, helaas is The Long Dark Hall nog niet beschikbaar op Netflix in Nederland.
