The cabbies are astonished when Jim (Christopher Lloyd), a burned-out relic of the 1960s whose appearance and lifestyle can be charitably described as "unkempt" abruptly turns over a new leaf. Virtually overnight, Jim has brought perfection, order, and expensive creature comforts into his life--and he's even begun to take baths and change his clothes. The reason? Well, it seems that Jim had earlier picked up a couple of passengers who were discussing the "secret of success." Future Miami Vice producer Michael Mann also appears in a supporting role.
