Detailed Explanation
Annie K.'s murder is the key that unlocks everything. She was a local Indigenous woman and activist who discovered the pollution cover-up. When she broke into Tsalal to find proof, the scientists killed her and hid her body in the ice caves. Her boyfriend Raymond Clark helped cover it up out of fear. Annie's murder was the original sin that set everything in motion—the cleaning women eventually learned the truth through piecing together clues, leading to their revenge on the scientists. The spiral symbol isn't supernatural; it's the mark of Annie's activism that haunts everyone connected to her death.
