Kathleen Hannah is the lead singer of the punk band bikini and the female dance punk trio Le Tigre (Tiger). Her voice stands out across the United States as a tenacious and unbowed feminist punk (riot grrrl). Later, she became one of the most famous and outspoken benchmarks of feminism, a milestone of the times. Her critics want her to shut up early, and her fans hope she never will. Hannah disappeared in 2005, which made many people feel extremely confused. "punk Singer" reviewed 20 years of video archives, through Hannah's private interview, led the audience to embark on a magnificent journey of contemporary music, but also opened a window for viewers to see the life of the intrepid hero.
