Robin Hood is described as a sweeping, romantic adventure, a modern take of the classic tale that brings historical authenticity, psychological depth, and a heightened focus on the relationship between Rob and Marian.

In the series, following the Norman invasion of England, Rob – a Saxon forester's son – and Marian, the daughter of a Norman lord – fall in love and work together to fight for justice and freedom. As Rob rises as the leader of a band of rebel outlaws, Marian infiltrates the power at court, as both work together to thwart royal corruption and bring peace to the land.
