Robyn and her friends prepare for Lionheart Day, a festival honoring Sherwood's fallen leader and Little John's mentor; just as Robyn hopes for a return to normal life, Lionheart's killer, the infamous Guy Gisbourne, returns from prison.

When Chet Prince mistreats Alan's friend Elmore, Robyn and The Hood decide to crash his birthday party and steal from the richest playboy in town.

With Prince's purchase of Sherwood complete, the Sheriff gives Robyn and her friends mere hours to evacuate; instead, Robyn joins forces with Tressie, Jill and her neighbors to make a final stand against the Sheriff.
