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.

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.

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.
