Batman: DarKnight was another idea for a sequel to Batman & Robin (after Batman Unchained was scrapped). Lee Shapiro and Stephen Wise drafted a script, and Joel Schumacher had also signed to direct. 
Bruce Wayne is in self-imposed seclusion from life, because he feels he has lost his greatest weapons in the fight against crime: his mystique and his enemies' fear. Dick Grayson attends Gotham University, trying to discover who he is apart from his guardian and unwilling to return as Robin without him. Meanwhile, Dr. Jonathan Crane uses his position as professor of psychology at Gotham University and as resident psychiatrist at Arkham Asylum to conduct his experiments in fear. During a vengeful confrontation with a colleague, Dr. Kirk Langstrom, Jonathan Crane unknowingly initiates Kirk's transformation into the creature known as Man-Bat. The unsuspecting citizens of Gotham scream for Batman's head, believing that Man-Bat's nightly hunts is the Dark Knight's bloodthirsty return to action. Bruce dons cape and cowl once more to clear his name and solve the mystery behind these attacks. Eventually, Dick ends up in Arkham Asylum under Crane's unsympathetic watch, and Kirk struggles with his "man vs. monster" syndrome as he longs to both reunite with his wife and get revenge on Crane.
