Everybody around lawyer Mary DiNunzio has decided she isn't allowed to be a Young Widow anymore, even though she didn't know there was an official cutoff. They're all trying to fix her up -- her South Philly Italian parents, her best friend Judy Carrier, even the office security guard.

All Mary wants to do is immerse herself in a case everybody else calls "The History Channel", a pro bono representation of the Brandolini estate. The roots of the matter sink deep into the past, when Amadeo Brandolini emigrated to Philadelphia, started a family, and built up a small fishing business. At the outbreak of World War II, Brandolini was arrested by the FBI as part of a mass internment of Italian-Americans and was sent to a camp in Montana, where he eventually committed suicide. Now, more than sixty years later, his son's estate hires Mary to sue for reparations.

Mary vows to vindicate Amadeo even though it won't be easy. With only a lock of hair, an old wallet, and a sheet of paper filled with odd doodles to go on, the tenacious lawyer begins to research the case but finds instead puzzling new questions. Someone doesn't want Mary to find the truth, and before long, her life is threatened. Suddenly, the quiet, squeaky-clean good girl who never left Mercer Street is risking life and limb to finger a killer and lay a beloved ghost to rest.
