NBC‘s Who Do You Think You Are? returns this month and Billy Porter will dive into a family murder. The multihyphenate will be featured in the new season’s premiere episode.

The episode will follow Porter as he enlists the help of a family historian and genealogist to learn the truth behind the 1923 murder of his great-grandfather. 

An official episode description reads, "Billy’s research takes him through conflicting accounts of what happened, before he discovers a local African-American newspaper that lays bare the appalling truth of his grandfather’s death and the community uproar that followed."

The upcoming season of Who Do You Think You Are? features several A-list stars, including Allison Janney, Zachary Levi, Nick Offerman, Billy Porter, Zachary Quinto and Bradley Whitford.

The new season premieres Sunday, July 10 at 7 p.m. ET/PT on NBC. Episodes will stream on Peacock the following day.
