Robin Hood (2006) - 2x03 - Childhood

When a group of boys accidentally stumble on Gisborne's weapons testing site, all but one are taken prisoner. Daniel raises the alarm and Robin hatches a plan, but with Gisborne armed to the hilt in an indestructible suit of armour, a rescue attempt is more difficult than it might first appear and Robin must think fast if he's to save a boy's life and stop a vital part of the Sheriff's war machine.
