Told through a series of vignettes, Bloom's stories involve a witch, a giant, a haunted forest, and yes, a big fish. A self-described small-town hero, Bloom explains how he left home at 18 determined to experience anything and everything life could dish out. He worked for the circus, took on daring assignments as a WWII soldier, and rambled across the country as a zany traveling salesman. Utterly unbelievable yet magical and delightful, Bloom's stories just don't translate to his son Will (Billy Crudup) who wants to know his dad's "true" life story. But little by little--through increasingly outlandish tales at which Will cannot resist smirking--the two begin to understand each other, and Bloom weaves his stories into their genealogical fabric.
