Earlier this week, Netflix announced the arrival of a surprise new sci-fi drama called The OA. The eight-episode series, which is released on the streaming site this Friday, follows the story of a missing blind girl named Prairie Johnson. After disappearing from her hometown without a trace, she returns seven years later with her sight restored. 

The mysterious first trailer was released on Tuesday – though it didn’t really give all that much away. To remedy that (or to baffle you even more), Netflix has now released three more cryptic clips from the series. The 39-second vignettes – titled “The Others”, “The Scientist”, and “The Little Girl” – hint at Prairie’s dangerous past, and include a cameo from Brit actor and MC Riz Ahmed.

The OA was written by Zal Batmanglij and Brit Marling, with the latter also taking the lead role of Prairie Johnson. Emory Cohen (The Place Beyond the Pines), Scott Wilson (Junebug) and Jason Isaacs (Harry Potter) also star. 

Watch all three clips below, and catch the full series on Netflix from tomorrow (December 16).
