Himmelsdalen - Season 1

Helena and her twin sister Siri have long lived separate lives. As a reunion approaches, Helena says yes and travels to an idyllic resort in the Italian Alps, but it quickly turns out that Siri has her own agenda with her invitation.

Helena becomes painfully aware of Himmelsdalen's main activities. She desperately tries to prove her true identity, but the institution's staff dismiss her claims as another of Siri's manipulative tricks.

Doctors disagree on how to interpret "Siri's" sudden behavioral improvement. Helena realizes that she can take advantage of her fellow prisoners' fear of Siri and learns of a secret organization that can pave the way for a possible escape.

The doctors' actions suggest that they are starting to take Helena's story seriously, but in reality they are only looking to confirm their own treatment theories. Enzo has understood that Helena is telling the truth and sharing her escape plan.

The young guide turns out to be anything but reliable, but confidence in Enzo remains. Helena receives valuable information about her sister during the sessions with Silva and a new plan to prove her identity begins to take shape.

Helena receives for the first time a sign of life from Siri, who apparently has no plans to return. The escape is imminent, but first another risky mission awaits, as Helena refuses to leave Himmelsdalen without having found the hammer.

Helena's newfound expectations are shattered when she is reached by the news of her own death, but suddenly Margot emerges with a new spark of hope. At the same time, Redpath and Fisher are trying to uncover evidence in the hope of saving the facility's reputation.

Helena wins over Silva on her side, but an accident happens when he tries to leave the facility. Now all that remains is for Helena and Enzo to carry out their escape attempt - and they are both prepared to do so at any cost.
