HBO Max Original Series
After a global event causes the oceans to recede by hundreds of miles, new, uncharted lands emerge. Michael B. Jordan is Commander Jaxen Reed, a former naval officer leading an expedition into the "Deep Dry"—the newly exposed seabed. Shay Mitchell plays Dr. Aris Thorne, an unconventional marine biologist who suspects the water didn't just disappear, but was "pushed" by something sentient. As they navigate salt-crusted canyons and skeletal shipwrecks, they encounter a primitive, territorial civilization that has lived in the depths for centuries.
