Some families have reunions this one has alibis! In this thrilling 1945 endeavor, Charlie Chan (Sidney Toler) finds himself at odds with an entire family, any one of whom could be a killer!
"Helped" by his pseudo-intellectual Number Four Son (Edwin Luke) and his panicky partner Birmingham Brown (Mantan Moreland), Charlie investigates the recent murder of a brilliant but much-loathed scientist (Frank Reicher) who invented a gas that makes wood as strong as steel. But the investigation is anything but elementary, as Charlie sleuths his way through suspicious scientists, sultry sisters, a silent cousin and a butler with a very stiff upper lip!
This time around, Charlie Chan (Sidney Toler) investigates the murder of a renowned, loathsome scientist, surrounded by a family that has alibis instead of reunions.
