Saga and Martin are quarantined, but when the test results come back negative, they’re cleared to leave the hospital, and thus continue their investigation. They’re assisted by a Swedish and a Danish officer, Rasmus and Pernille. Someone posts a video online where four individuals wearing animal masks use signs to claim responsibility for the plague. This coincides with several reported deaths as a result of eating, among other things, poisoned apples. Saga and Martin are quick to connect the two cases. And they realize this is just the beginning… Martin decides to try to confront Jens a second time. Saga tries to be the perfect girlfriend, but her boyfriend, Jacob, sees right through her.
