Torchwood are chasing aliens down the M4, when Jack accidentally blows a hole in the Severn Bridge, and the SUV hits the water. Whilst submerged Jack, Gwen and Ianto hear a strange noise, which, back at the Hub they realise is a cry for help. They track the cry to its source which turns out to be the deepest part of the Ocean – the Mariana Trench. Ianto rings old Torchwood flame, Carlie Roberts, who’s an expert in marine geology, and Jack pulls strings with the US government to get them all on board the USS Calvin, an Arleigh Burke class destroyer, which is heading for the Trench. From there they board the Octopus Rock, the only submarine built to withstand the pressure at that depth, and follow the signal. But when the Submarine crashes, the team are left at the mercy of a hungry alien.

    Decent! Not super invested in it, but I liked it.

    This audio is a lot of fun!!! Carly gives a sneak-peek into Ianto’s backstory and how so few people survived Canary Wharf. I also liked the “Janto angst” of this story with Ianto saying he loves Jack but that he’s resigned to the “reality that Jack will leave him someday.” It’s not much but I liked how this audio gave insight into how Ianto feels about their relationship.

    While the storyline it self was okayish, I loved that we got really great character moments. The story is worth that alone. I wish those audio dramas were longer than 45 minutes, it would help the storytelling. But overall I enjoyed this one a lot.
