Bad Bob Zimmermann is a master thief. Jack has to wrestle with his father’s legacy of cat burglary, and becomes a Robin Hood-esque figure, robbing only those who he figures will not be significantly hurt by this. When stealing the famous Knight Sapphire, he meets Beauchamp Knight, who wants to rebel against his parents and begs to join him in his quest. Slowly their band of thieves grows, until they run up against Agents Eric Bittle and Larissa Duan, the FBI agents dedicated to catching them and stopping them once and for all.
