The crew is in trouble! An anchor hit sealab and its starting to flood and air is running out! how will they ever fix this!

Sealab members are out trying to capture an electric manta ray when they see some strange figures who they figure out are there drilling for oil, with Sealab's permission but without the crew's knowledge. They attempt to try to get the men relocate the oil drilling to another field miles away from sealab but the drillers refuse. Then a tsunami hits and their oil drilling operation is destroyed, the episode is called Backfire because if they would have moved the drilling operation they would have been fine :)

The crew of Sealab are testing a new submersible vehicle called the ""Crystal Ball"", which is made out of mostly glass and is supposed to be better than conventional submersibles and dive deeper. They are given a mission to place a seismograph unit at the bottom of a deep part of the sea, but for some reason the unit stops functioning. They go back out with a second replacement seismograph unit and realize that a giant squid had taken the first unit and used it for material for its rock home. The squit catches the Crystal Ball and the crew is stuck trying to escape from it's grasp. They eventually get free and the new seismograph unit works.

The Sealab team meet Alex, an archaeologist who has dedicated the last 7 years to finding the sunken ship 'Viking', which sunk over 100 years ago. It's rumored that the ship was carrying some aztec treasures. Alex's brother Chuck is very excited by the discovery, and his excitement is getting in the way. Sealab follows rules and guidelines that guarantee safety, but prevent Chuck from finding the treasure faster. Alex is willing to cut his losses if lives could be lost, but Chuck will not let the last 7 years of his brother's life be for nothing...

Human complications make dealing with the mechanical ones more difficult when cargo sub "Aquarius" crashes into Seamount and endangers the Sealab complex.
