Batman: Under the Red Hood
At his manor in Sarajevo, Bosnia, Ra's al Ghul realizes his mistake in allying with the Joker and using him as a distraction for the Dynamic Duo while Ra's himself tried to cripple the world economy by destroying financial districts in Europe. Meanwhile, the Joker has kidnapped Jason Todd, the second Robin, and brutally beats him with a crowbar in an abandoned warehouse while Batman races there. The Joker then leaves Jason locked in the warehouse with a bomb. Batman arrives just in time to watch the warehouse explode, killing Jason.
