Robin disappears from Hudson University prompting Batman to search for him. The trail leads to a dusty old mansion on the outskirts of Gotham. Inside the house, Batman faces several traps and illusions including Robin's demise and his own funeral. Eventually, Batman is trapped and the villain behind it is revealed as Doctor Tzin-Tzin who is now working for the League of Assassins.

Batman is trapped in a glass tube with a bomb. Robin is nearby. Batman escapes the trap, then stalls for time until Robin can recover. They capture Doctor Tzin-Tzin and take him out of the house. However, Tzin-Tzin suddenly disappears and the house explodes behind them.
