Following the large audience for the third-season premiere of the US-version of Who Do You Think You Are? - starring Martin Sheen - the second episode focused on Marisa Tomei.
Tomei's story concerned her murdered great-grandfather, and the false belief held by her family about the event's circumstances.
Her odyssey takes her from Brooklyn to Tuscany, Elba, Castiglioncello and Lucca to find the truth about the event, and her mother's BIANCHI and CANOVARO families. Her father, Gary, had already done extensive research on the TOMEI family tree.
