The Internal Affairs box set conclusion delivers high drama and emotional intensity.

Fresh off passing her ambulance driving test, Indie's triumph turns to terror when her accelerator jams on the way back to the Emergency Department.  In a catastrophic collision, she pins Scott against a wall, leaving the team scrambling to save one of their own. 

When the ambulance driven by Indie, barrels through the doors of the Emergency Department - quite literally - crashing into the heart of the hospital, Rida is forced to confront a trauma that cuts deep into her past.  The chaos of the crash is just the beginning, as the fallout brings back painful memories she's tried desperately to bury.

Rida finds herself at the centre of two devastating crises.

In a powerful and emotionally charged turn, Rida makes a life-altering choice to break her silence and publicly confront Russell's misconduct, knowing full-well the personal and professional risks.  As the walls close in and the stakes reach a boiling point, Rida's courage shines through in a bold stand that could change everything.

Stevie faces a quiet reunion with a figure from her past, stirring memories she'd rather forget.  As Stevie nervously prepares for her first chemo session, the weight of her anxiety and this unexpected encounter collide, testing her resilience.

Will Stevie find peace amidst the turmoil?

Ngozi grapples with the guilt and shame of falling off the wagon, her inner turmoil threatening to unravel her carefully rebuilt life.  As she navigates the bustling Emergency Department, the weight of her choices forces a raw confrontation with her past mistakes.

Flynn is on a quest to seek forgiveness. 

Last in series.
