The Call from the Past

Episode begins, Roger and Angel are trapped in a building buried under the sea, one of a string apparently created by the Event. Three days earlier, Roger is trying to negotiate to bring down the price of fish for the people outside the domes. He learns that the reason fish is so expensive is because the fishermen won't go out to fish because they are scared of a sea titan in the water. To check out the claims, Roger finds a man who has built a submersible and tries to hire it, but is told it needs to charge up. While there, he sees the ‘servants of the sea titan', who are actually divers with masks and flippers, but they run away. When he returns later to use the sub, the owner tells him it has already been rented to a woman. Roger turns to find the woman is Angel, and before she can pull away, he manages to jump into the sub and they go down together. While exploring the city under the sea, they are attacked by the divers who place a bomb on the sub.
