This story takes place in the year 1969. An aging actor named Rick Dalton has been stuck playing the role of antagonists in various films for several years. He was once the star of a Western television series called Bounty Law in the 1950s, but his time in the sun has long passed. He often confides to his best friend and stunt double Cliff Booth that his career is effectively over. Despite his dire situation, Rick lives in a comfortable house on Cielo Drive. He realizes he may have a second chance on his hands when two rising talents, Sharon Tate and her husband, Roman Polanski, move into the large house next door to him.
Sir Lionel Frost has been doggedly pursuing countless mythical creatures in an attempt to join a society of great men led by his rival, Lord Piggot-Dunceby. His last attempt at discovering the Loch Ness Monster resulted in a resounding failure, for his camera was shattered by the creature. With nothing to show for their endeavor and nearly having been eaten by the monster, Frost’s investigative partner quits. While considering his next course of action, Frost discovers a letter from somebody claiming they have irrefutable proof of Sasquatch’s existence, asking him to come to the state of Washington. He then makes a deal with Piggot-Dunceby that would allow him to join the society if he can prove the creature is real.
