Gentleman of leisure Bunny Manders is running from a gambling debt-and the men to whom he owes it-when he chances upon former school chum AJ Raffles. Bunny learns Raffles is a brilliant criminal-a gentleman thief burgling high society-and they rekindle a mutual affection. In a rustic village, the reunited lovers meet detective Sherlock Holmes and his companion Dr John Watson. To rescue Bunny from financial ruin and physical harm, Raffles weaves threads of deceit, romance, and robbery to dazzle Holmes and intercept a delivery of precious gems. But intrigue can have tragic consequences, and before Raffles and Bunny can return to London with their prize a new disaster looms, so Bunny must rush to save Raffles from a violent end.
