Author Robert Louis Stevenson takes a trip to Napa Valley, California, in 1880 and gets involved in the exploits of a stagecoach driver who captures a hooded highwayman called The Monk. Supposedly inspired by a true incident, this offbeat Western based on Stevenson's The Silverado Squatters is a dandy, high-spirited adventure yarn.
