In an idyllic Australian seaside town, two life-long friends, Roz and Lil, live in close proximity, their bond as deep and complex as sisters. Both women have sons, Tom and Ian, who have grown up together, their friendship mirroring that of their mothers. The serene landscape and tight-knit community conceal the unconventional and intense nature of the relationships between these four individuals. A series of events leads to a surprising and controversial turn in the dynamics between the sons and their mothers, challenging societal norms and the boundaries of traditional relationships.

The shifting relationships cause ripple effects, forcing each individual to confront their desires, regrets, and the fear of judgment from those around them. The intimate connections that develop test the limits of their close-knit community's acceptance and their own self-understanding. As these relationships evolve, the four characters are thrust onto a path of emotional turmoil and discovery that threatens the stability of their lives and the depth of their familial bonds. The picturesque setting contrasts sharply with the internal chaos, as each character struggles to reconcile their actions with their consequences, setting the stage for a profound exploration of love, friendship, and personal transformation.
