DiepCity explores the struggle of four young women trying to make their way in the world. Also, how they were forced into crime while in high school, just to make ends meet.

The world comes crumbling down for small-time house burglar Nox (played by Nozuko Ncayiyane) after her bright, straight-A student younger brother Sibusiso (Tshiamo Molobi) is fatally shot during a house robbery he was not supposed to be part of in the leafy suburbs of Johannesburg. The robbery was set up by rogue security guard and low-level gangster Mgedeza (Mduduzi Mabaso) and carried out by Nox and her crew. After doing time behind bars following her arrest, Nox returns to find her family still living in a shack after her alcoholic father Bonga (Hamilton Dlamini) lost his job, while her mother Thandiwe (Dawn Thandeka King) - who has not forgiven her for Sibusiso's death - continues to work as a domestic worker. Will Nox manage to mend relations with her parents? Will her circumstances force her back into a life of crime or will she turn her life around?
