A young man (Douglas Walton) is due to go to the gallows for murder in a few days but his sister Pamela (Drue Leyton) is still desperately trying to prove his innocence. Charlie Chan (Warner Oland) is in London on another case but Pamela persuades him to help. Charlie heads up to the country house where the murder took place.
He encounters some resistance from the upper class stereotypes assembled there for a hunting party. While they hunt foxes, Charlie hunts clues. But soon his own life is in danger...
This is an excellent instalment in the Charlie Chan series, though Charlie is on his own this time with no sons to help. Charlie expertly unravels the plot and ends up tricking the real murderer into unmasking himself. Great film indeed!
