They’ve been around for over 150 million years — long before humans evolved. The crickets. Tiny, unassuming, and among the first animals on Earth to use sound to communicate.

This film follows Dr. Rohini Balakrishnan, an IISc scientist whose lifelong fascination with the natural world led her to the songs of these ancient insects. From her early research in animal communication to countless nights in the Western Ghats, Rohini has spent over two decades decoding the hidden world of tree crickets — their songs, their behaviors, and their role in the web of life.

Her journey took an unexpected turn when a newly discovered species of tree cricket in Mexico was named after her — a gesture of recognition from scientists halfway across the world. But beyond that honor lies a deeper story — of listening, patience, and the urgent need to protect the small lives that sustain our ecosystems.

Through her eyes, we hear the delicate music of evolution — how crickets sing, why they matter, and what their survival tells us about our planet’s fragile balance.

Because in their songs lies a 150-million-year legacy — and a reminder that we share this Earth with voices far older than our own.
