Tim is in search of a celebrity for the grand opening of his antiques shop, and it just so happens that his very first customer is sports presenter and Strictly Come Dancing champion Ore Oduba, who asks Tim if he can mend his ancient golden arrow. Tim steps inside his very special grandfather clock, which takes him back in time to Sherwood Forest during the days of Robin Hood and his band of merry men. On arriving, Tim is greeted by Robin himself. Robin is suffering from a broken heart. He has mysteriously lost his famous bullseye aim and with it the love of Maid Marion. Tim must get to the bottom of the mystery, but local tyrant and shouty killjoy the Sheriff of Nottingham is determined to drive him out of town. Can Tim get to the bottom of this skullduggery to help Robin regain his archery prowess and win back the love of Maid Marion? Will he be able to repair the broken arrow and secure Ore Oduba to cut the ribbon at the grand opening of Tim's Antiques? Only time travel will tell...
