Passionate about ocean life, a filmmaker sets out to document the harm that humans do to marine species — and uncovers an alarming global conspiracy.

Sword Fishing is a 1939 short documentary film about a group of fisherman, including Howard Hill, "the world's greatest archer," who go in search of marlin off the California coast. With fishing line attached to his arrow, Hill plans to spear the fish, which would then be brought aboard the boat by rod and reel. In 1940, the film was nominated for an Academy Award for Best Live Action Short Film, One-Reel at the 12th Academy Awards.
