Robotnik has arranged a museum exhibit of the Royal family goblets. Knowing that Sonic, Sonia and Manic will want to reclaim their family's treasures, Robotnik expects the heirlooms will serve as perfect bait to finally capture the Hedgehogs. Sonic and his siblings are aware that this is most likely a trap and devise a counter plan of their own to avoid getting caught. The Hedgehogs' mission falls apart and when Sonic and Manic are taken prisoner, Sonia must choose between which brother she should risk rescuing from the robotization chamber first, Manic or Sonic.
- The plot and title of this episode are possibly a reference to the book Sophie's Choice, in which a mother, interned in a concentration camp during the Holocaust, must choose one of her children to survive while sending the other to die.
