One timeline will tell the tale of Jamie Fraser’s parents, Brian Fraser and Ellen MacKenzie, with a focus on their lives and their relationship. The other timeline will focus on Claire’s parents, Julia Moriston and Henry Beauchamp, along the same lines.That means the series will likely be set both in World War I-era England and 18th-century Scotland simultaneously. The season will likely explore the surprising convergence of these separate timelines as revealed in the trailer - Claire's parents will accidentally travel back in time to 1714 Scotland.There, their paths will intersect with both the MacKenzie and Fraser clans. This, however, causes unexpected complications as each couple faces their struggles to stay together or return to each other across time and space.Outlander: Blood of My Blood season 1 will be released on Starz on August 8, 2025.
