From the Indian Ocean's clear blue atolls to the icy waters of the St. Lawrence River, we embark on an epic expedition with the Cinémarine team to capture the remains of ten of the world's most spectacular underwater disasters.

With the most advanced technology and state-of-the-art equipment, amid danger and uncertainty at times, we take a deep dive to explore—up close and in 4K—these mysterious wrecks, coming up for air only to hear the testimonies of crew members and passengers who survived to tell the tale.
