Wattle Avenue looks like the perfect suburban street - tidy gardens, friendly neighbours, and a community that prides itself on knowing everything about everyone. Behind the welcoming smiles and endless gatherings, however, lies a neighbourhood fuelled by gossip, secrets, and quiet desperation. When a mysterious couple moves into Number 15, the residents grow suspicious. As tensions simmer and lives begin to unravel, long-buried truths slowly rise to the surface. Quiet Joan, the woman with the immaculate garden and a past no one understands, visits a nursing home every day to care for her sister, Josie - a sister whose tragic history connects them to a crime that changed everything. Across the street, Frances, exhausted by her crumbling marriage, stumbles into Joan's carefully guarded world, unknowingly reopening wounds decades old. But somewhere far beyond Wattle Avenue, justice is already in motion. Because some sins are never forgotten. And sometimes karma arrives long after the neighbourhood has stopped looking.
