Tatiana Maslany has revealed that the clones are in further danger in "Orphan Black" season 4.

The latest promo video released by BBC America highlighted the warped fairy tale elements that have been naturally weaved into the plot of the sci-fi drama. This time, "Orphan Black" season 4 is using references from "Alice in Wonderland" to showcase the chilling drama that the LEDA clones will encounter up ahead.

In the 30-second trailer, Maslany's numerous characters in the series were seen in various frightening situations. Cosima was seen falling down the ground, while Alison was being attacked by an unknown person. There was also a monkey doll caught on fire. Could this mean that LEDA sisters will continue fighting for their lives while embarking on a dangerous hunt to find Beth Childs?

"Orphan Black" season 4 is reportedly centered on the LEDA clones' attempt to look for the original clone. Yet each new discovery brings them to another life-threatening situation. The season will also introduce a new clone called MK, described as a loner with a mask who has been following the trail of her "sestras" from the start.

However, little is known about MK. Will she help the other clones get the answers that they have been searching for, or will she bring them to further destruction?

Meanwhile, part of the press release from BBC America for "Orphan Black" season 4 reads:

"Season 4 of the drama will see leader-of-the-pack, Sarah, reluctantly return home from her Icelandic hideout to track down an elusive and mysterious ally tied to the clone who started it all -- Beth Childs. Sarah will follow Beth's footsteps into a dangerous relationship with a potent new enemy, heading in a horrifying new direction. Sarah's old habits will begin to show again being in under constant pressure in keeping everyone safe. Sarah will find herself estranged from the loving relationship that changed her for the better."

"Orphan Black" season 4 is slated to return in April 2016.
