Fourth Profession, The
After a visiting alien unexpectedly shows up in a Los Angeles bar, bartender Ed Frazer awakes the next morning with the strangest hangover of his life. Ed barely remembers taking the gift offered by the alien; mysterious pills that flood his brain with the knowledge and skills of an alien profession: spaceship captain, teleporter, translator... now Ed can't remember how many pills he took, or if the confusing overload of information in his head reveals the terrible secret of the aliens' mission...
