Their job is to keep passengers on the Sao Paulo underground safe. But, once a month, instead of patrolling the platforms, nine security guards treat commuters to a concert.

The band is so successful that more members of staff want to take their place in the spotlight. 他们的工作是维持Sao Paulo的地下旅客安全。但是,曾经有一个月,九名保安不巡逻,而为每日往返的上班族奉上一场音乐会。他们把车站作为聚集之地,演奏森巴,摇滚和歌剧。这个乐队非常成功,很多保安工作人员都想代替他们,成为聚焦灯下的一员。
