A group of barristers and trainee lawyers vow to pursue justice and ideals, but the process is fraught with difficulties. Regarded as the "Condor Heroes" of the legal world, barristers Marcus Fan (Ben Wong) and his wife Vivian Cheung (Elaine Yiu) have taught many students. Among them, Giselle Tong (Grace Chan), Brittany Fok (Jeannie Chan) and Quinton Chow (Louis Cheung) are Marco's favourites. Giselle's classmate, Holly Tsang (Moon Lau), is a trainee solicitor at Vivian's law firm, while Chris Yiu (Stephanie) Ho trains under barrister Duncan Yam (Timothy Cheng). Brittany's elder half-sister, Ashley Cheng (Natalie Tong), has an affair with the married Duncan and later switches over to work for Marcus. With each of them using their own methods, how do these rookies become qualified legal practitioners, in a journey that is full of struggle, doubt and tough choices about their future? Theory turns into practice as they handle tricky cases and experience success and failures, while also dealing with love, family and friendship problems every day. Their biggest test arrives when legal standards challenge their personal orientations.
