In the decaying heart of an Edinburgh slum, two cockroaches—Dougie "Dreich" Dreich and Lachie "Loony"—cling to existence amidst filth, addiction, and despair. Drawn together by the remnants of heroin left behind by their tenant, Johnny "Scab" McBride, they form a twisted bond that spirals into madness. As Lachie’s chaotic life unravels, dragging Dreich deeper into the void, the flat becomes a claustrophobic prison, echoing with the ghosts of lost souls and forgotten dreams.

*Dregs* is a harrowing descent into the darkest corners of the roach psyche, where addiction and hopelessness consume all, and the thin line between life and death fades into oblivion. In the end, all that remains is the suffocating silence of lives wasted, a haunting reminder of the futility of existence.
