Cara thinks the radio station is a waste of time until she arrives at Raw's studio and realises this is where she could have an impact. They need her organisational skills. But disaster strikes at the Raw FM party and Cara's good work is forgotten, until Sarah comes to her sister's defence. Blood is thicker than water, after all. But is RAW big enough for the two of them?

Sarah spends more time at RAW FM than she does at her home. On the air Sarah the stutterer turns into Sarah the ultra-cool DJ. She stretches the boundaries of political correctness to the limit when she permits callers to have their say no matter what they want to say. This total 'free speech' puts her colleagues in danger and the licence in jeopardy.
