Far out in the Arabian Sea, where the waters plunge many thousands of metres to the ocean floor, lies a chain of bewitching coral atolls–the Lakshadweep Islands. Vikram and Aditya dive into lagoons with crystal-clear water and reefs that are deep and shrouded in mystery. But when they stumble upon a devious kidnapping plot, their idyllic holiday turns into a desperate struggle for survival. Forced out into the sea in the eye of a raging storm, they endure a shipwreck, only to be marooned on a remote coral island.
