Big Brother is watching you - literally - in the new teaser for Orphan Black season four.
BBC America has released a creepy promo comprised of a single extreme close-up of an eye, which is not all it appears to be.
The new season of the Canadian sci-fi will see Tatiana Maslany's Sarah return from the Icelandic hideout she escaped to at the end of season three to track down an ally tied to the clone Beth Childs.
"Sarah will follow Beth's footsteps into a dangerous relationship with a potent new enemy, heading in a horrifying new direction," the official synopsis reads.
"Under constant pressure to protect the sisterhood and keep everyone safe, Sarah's old habits begin to resurface. As the close-knit sisters are pulled in disparate directions, Sarah finds herself estranged from the loving relationships that changed her for the better."
Orphan Black season four will air in the US on BBC America in April 2016. In the UK, season three was made available in its entirety on BBC iPlayer in September this year.

Earlier this year, co-creator Graeme Manson shared that he has an idea of how the show will end.
"We've kind of always had an end point," he revealed. "Like an end to the mystery."
Meanwhile, the show's lead Maslany has said she feels a "strong sense of responsibility" to Orphan Black's LGBT fans and praised the fact that the series "isn't preachy, it just is".
