Life in Bodega Bay, famous as the setting for Alfred Hitchcock's The Birds, has been quiet for antiques dealer Toby Sandler-until his new business partner is found dead in the harbor. Soon, the local sheriff discovers that the victim's recently acquired Hitchcock artifacts and a painting of an angel have mysteriously vanished. Toby and his wife, art historian Nora Barnes, are enlisted to aid the investigation. As they dig into tales of the area's past and encounter perplexing clues that are both criminal and otherworldly, the couple contemplates whether some mysteries are too deep to solve.
