A middle-aged lawyer works and lives alone in a dreary apartment. One cold and rainy day, a dishevelled man breaks in and entrusts him with a small package. After that the lawyer continues to be plagued with break-ins and unwelcome visitors. When one day his girlfriend is stabbed to death, the lawyer sets out for revenge. Drum is a disturbingly bleak, dreamlike and Kafkaesque picture of the life in contemporary Tehran.
