[Part 1] At age 19, Mark Everett - better known as E, the frontman of geek-rock outfit Eels - found his scientist father Hugh Everett dead from a heart attack. Everett senior was the underacknowledged quantum physicist who first developed the theory of parallel universes. Now, 25 years after his father's death, Mark wants to get to know this emotionally absent savant who rarely spoke. He does this by interviewing his dad's friends and colleagues. It's a cathartic quest punctured with moments of raw sadness and deadpan witticisms from the cigar-smoking singer. But this isn't just a compelling family saga. It's a one-layman mission of scientific discovery.
