chunk: During initial investigation of the Montana, a power outage in the team's submersibles leads to Lindsey seeing a strange light circling the sub. At the same time, one of Deep Core's crew, "Jammer", damages his breathing apparatus in an apparent panic, and falls into a coma. This prompts the admiral in charge of the operation to send Lt. Coffey, the SEAL team leader, to take one of the mini-subs and recover a Trident missile warhead from the Montana, just as the storm hits above. Coffey does not get permission from the Deep Core crew. The Benthic Explorer, which Deep Core is tethered to, is rocked by the storm, and the cable crane is torn from the ship. The crane falls into the trench and, without the mini-sub to disconnect the cable, Deep Core is dragged towards the trench, stopping just short of it. The rig is partially flooded, killing several crew members and damaging its power systems. Coffey shows little remorse when he and his SEALs return to the damaged base.
