Jane Seymour trades her acting hat for a detective’s cap in Relative Secrets, a new unscripted series digging into the hidden histories of everyday American families. Premiering Monday, June 2 at 10 PM ET on both BBC America and Acorn TV, the four-part investigative series sets out to unearth long-buried family mysteries—and connect those present-day relatives to their UK heritage.

Each hour-long episode focuses on a different family, guided by Seymour and archaeologist Natasha Billson, who leads the on-the-ground investigation. Expect a mix of true-crime drama and genealogical deep dives, as the series unearths secrets ranging from wartime heroism to, yes, even a serial killer. The premiere kicks off with a 99-year-old WWII veteran whose past holds more than a few surprises—a solid entry point for anyone who’s ever wondered what skeletons might be hiding in their own family closet.

Relative Secrets looks to hit that sweet spot between uncovering shocking twists and exploring the ripple effects those revelations have on families today. With its focus on UK connections, the series also taps into the current boom in ancestry research, giving viewers a chance to see how the past shapes the present—one unearthed secret at a time.
