Bannerman Independent School's known for its reputation and status. Only DGM, made up of four disparate but determined students, dare to reveal the truth.

DGM get to work on a new mission, bringing down Ronny Kent. Olivia's relationship with Donte is put at risk because of it.

Shocking news shakes the students of Bannerman to their core. Could DGM be in the frame for a terrible crime they didn't commit?

Margot's past comes back to haunt her, Bree's forced to spend quality time with Rex, and DGM set to work investigating their number one suspect.

Kitty is faced with a personal dilemma as the pressure mounts on DGM to expose the truth about a criminal, but not a cuddleer.

Bree gets benched, Ronny's memorial gig prompts many to seize the day and a suspect makes their way to the top of DGM's list.

Olivia's secret is revealed, Kitty competes in a fencing match, Bree realises she has a boyfriend and a loss means DGM rethink their main suspect.

We flashback to when DGM began, while in the present they organise their most joyous prank yet. But then a suspect is arrested.

The Police are satisfied they've found the culprit despite a number of loose ends. Can DGM keep investigating when fractures threaten to tear them apart?

DGM finally learn the truth, but not without great personal risk and devastating consequences.
