Season 2 Episode 2

In his first mission since discovering the devastating truth about operation "Shah Mat", Robin launches a raid on the Castle. The Sheriff has stored all his "Shah Mat" funding in a medieval Fort Knox that is the new Strong Room, and he's preparing to make a final deposit before the Black Knights arrive to divvy up the silver. Having underestimated the Strong Room's deadly traps, Robin rethinks his attack - resolving to track down the original Strong Room designers - who have been mutilated to prevent them from leaking the secrets behind their brilliant designs. With the help of the now-blind designer Steven, Robin and his men learn the Strong Room's design secrets and work hard to get around them. Meanwhile, Gisborne has ordered Marian to look after Prince Frederick of Hanheim (Dexter Fletcher, Hotel Babylon), who has arrived to play in the casino. The Sheriff has no intention of losing to the Prince and when Frederick learns the Sheriff's plan to trick him by using fake dice in the casino, Marian gains a vital ally. Together with Robin and the gang, Frederick and Marian formulate a plan to rob the Strong Room. All Frederick must do is lose in the casino, but he ends up winning. Things aren't looking good for Robin in the Strong Room, either. Traitor Allan has leaked information about Robin's attempt on the vault and Gisborne has ordered modifications.
