Boston attorney Mary Ross, portrayed by Emily Rose from “Haven,” comes into possession of a house in Plymouth, Massachusetts, left to her by her great-aunt. Initially, she intends to put it on the market. However, her plans take a turn when she meets Everett Mather, a local historian played by Justin Breuning. Mather’s findings suggest that the property could be situated on the site of the first Thanksgiving, adding a layer of complexity to her decision.
