Joining the outlaw's fight against injustice is mysterious Brother Tuck (David Harewood) and Kate (Joanne Froggatt), a feisty Locksley girl. Each episode Robin leads the battle for a free world, but it's tough when corruption and evil sweep the land.

The King is absent fighting in the Holy Land and while his throne is empty, his treacherous brother Prince John (Toby Stephens) plots to seize it. The prince has his eye on Nottingham for his new capital and the country is on the brink of civil war. Can Robin save England for Richard and his people?

Tuck knows the power Robin has, but can he raise a people's army to follow him? Robin is both man and myth but what must he sacrifice to become the legend the nation needs? Loves are lost, lives surrendered.....

This is Robin Hood, but not as you know it. Take nothing for granted. The death of Marian was just the beginning....
