After the schools are shut down, Lan unwittingly finds herself involved in the guerillas' mission to save novelist Mao Dun. In the process, she meets Blackie Lau, the intrepid sharpshooter captain of the guerillas' Urban and Firearms unit. Taking notice of Lan's calm, smart nature, Blackie recruits her to join the guerillas. Chinese with English subtitles.
