Irving and his best friend and partner, Dick Susskind, go to extreme lengths to pull off the hair-brained scheme. The more outrageous the lies they concoct, the more believable they become and the more money gets thrown at them. Inspired by the unbelievable true story of the man who faked the authorized autobiography of Howard Hughes and nearly pulled off the media scam of the 20th century.
