Robin and the Outlaws arrive at a barn for Robin's birthday party, only to find that they are surrounded by The Sheriff's mercenaries and won't be let out alive. The Outlaws share their secrets with one another whilst the traitor, Allan A Dale, realises that The Sheriff and Gisborne are heading to the Holy Land to kill the King. Fearless Marian takes it upon herself to stop The Sheriff in his tracks while Allan must choose his allegiance. Will Robin realise that the mercenaries are merely there to distract him from The Sheriff's new dastardly plan, and will Allan come to his senses?
