On the morning of the 9th June, 1931, the HMS Poseidon, a British submarine, set out from Wei Hai Wei on the China coast to take part in a routine training operation. Due to a series of miscommunications, it collided with the SS Yuta, shattering Poseidon's hull. Within four minutes it had sunk to 126 feet. Eight men found themselves facing imminent death, trapped inside the forward torpedo compartment. Among them was a young Hong Kong Chinese Officer's Steward called Ah Hai. What happened in the next few hours would change maritime history forever. 

Escape from the Deep is a true story of bravery and survival, featuring one of Hong Kong's own, who sadly, has never been properly celebrated for his incredible courage. It's told in two documentaries produced and presented by Cruzanne Macalister.
