In 1878, archaeologist Hjalmar Stolpe uncovered a grave containing a large number of weapons and the skeletal remains of what seemed to be a great Viking warrior.

Join this team of experts as they examine the DNA results and complete a field investigation, uncovering the truth about the only archaeological discovery of a female Viking warrior and battle strategist known to date.
