250 ft deep lies the secret of Blue. Treasure hunters come in droves, lured by tales of a fabled treasure. No one has ever returned from the deadly depths of the Pacific Ocean. For not only is the treasure inaccessible; it’s guarded by deadly sharks. Aarav (Akshay Kumar), Sagar (Sanjay Dutt) and Sam (Zayed Khan), these three men with different motives find themselves diving deep into the murky depth to hunt for the treasure. As emotions run high and motives run deep, the dark side of human nature lays bared. And hundreds of feet underwater, Aarav, Sagar and Sam grapple, initially with sharks and then with the demons of greed, betrayal and above all, their own pricking conscious.
