The story is loosely based on the 11-day stint that mystery author Agatha Christie went missing in December 1926. After a massive manhunt was launched for the beloved actor, she was found at the Swan Hydropathic Hotel in Yorkshire, England, registered as Mrs. Teresa Neele from Cape Town, South Africa. The author never explained her unusual disappearance. The script is an action-adventure described as a cross between Sherlock Holmes and Romancing the Stone, using the event as a backdrop.
