The Joad clan, introduced to the world in John Steinbeck's iconic novel, is looking for a better life in California. After their drought-ridden farm is seized by the bank, the family -- led by just-paroled son Tom (Henry Fonda) -- loads up a truck and heads West. On the road, beset by hardships, the Joads meet dozens of other families making the same trek and holding onto the same dream. Once in California, however, the Joads soon realize that the promised land isn't quite what they hoped.

Despite warnings that the region is dangerous, Botanist Glendon (Henry Hull) travels to Tibet in search of the "Marifasa Lupina", a rare flower which blooms only in moonlight. Back in London, Glendon is visited by the enigmatic Dr. Yogami (Warner Oland), who tells him that a current rash of murders is the work of two werewolves. Yogami also claims that the only antidote is the blooming Marifasa flower, which keeps the werewolves from harming the ones they love. Glendon scoffs at Yogami's stories, until he next full moon!
