Inspired by the work of writer Arthur B. Reeve, this 15-part serial aims to uncover the truth about the mysterious disappearance of a scientist, the brilliant Paul Gironda (Robert Frazer), and his top-secret formula for concocting gold. It's up to illustrious gumshoe Craig Kennedy (Jack Mulhall) and newshound Walter Jameson (Rex Lease) to crack the case. Could the fiend known as the Clutching Hand be behind the abduction?
