Helgoland 513

An island community of pandemic survivors finds itself shaken when a baby is born.

Linus offers to embark on a dangerous mission to the mainland, and an alarm at the water treatment centre causes chaos on the island.

As Heinz returns from the mainland to Helgoland with a possible infection, Beatrice tries to calm him down while Marek attempts to develop an antidote.

Beatrice discusses the future of the island's rebellious youth, and Marek realises that the laboratory ship Linus spoke of is their only hope.

The wife of islander Ewelike, who lives on the mainland, applies for the island, but she has a rival, medical student Daniela. Linus' condition deteriorates.

Ewelike is severely accused by Beatrice, but Marek does not contradict her.
