Lora as Black Canary Lora is working as cop.  Her task is to prevent people from crossing a police line.  For that, a zone before that line has been created, that she gets to guard and where she can arrest or beat up people that enter and try to cross the police line.  Five guys show up and try anyways.  Big mistake.  Lora not only prevent them from crossing the police line, she ends up beating them up and arresting them in the process.
