Lionheart Day kicks off with a surprise as John Prince offers to bargain with Tressie over Sherwood's future; while Tressie and Prince negotiate, Robyn starts to suspect things are not what they seem when Guy Gisbourne returns to crash the party.

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.
