Overview: The provided synopsis for Season 16 is only one sentence: "Sixteenth series of the BAFTA-winning series". There is no narrative arc provided for Season 16. The general series description is that it is a British genealogy documentary series where celebrities trace their ancestry to discover secrets and surprises from their past.
Constraint Check: I must write 160-220 words for the overview. However, the source material does not contain enough information to reach 160 words about the narrative arc of Season 16.
Rule: "If a detail is not in the provided material, you omit it rather than guess." and "You never invent... plot points."
Conflict: The prompt requires a 160-220 word summary of the season's narrative arc, but the source only says it is the "Sixteenth series of the BAFTA-winning series".
