In the early 1840s, Wells Fargo employee Ramsay MacKay (Joel McCrea) comes upon a broken down carriage in the countryside and gives belle Justine Pryor (Frances Dee) and her mother (Mary Nash) a lift into Buffalo, New York, though he warns them he is in a hurry to make a delivery of fresh oysters. The ladies endure a very bumpy ride, and he arrives in time to enable his employer, Henry Wells (Henry O'Neill), to impress some bankers with the speed of his service.
