Citizen Kane
At the beginning of Citizen Kane, protagonist Charles Foster Kane (Orson Welles) dies, his last words being "rosebud." The movie follows a reporter, Thompson (William Alland), who attempts to uncover the mysterious meaning behind Kane's last words. "Rosebud" was the name of Kane's childhood sled, a representation of the innocence that Kane lost when his parents sent him into the city in hopes of making a name for himself.
