Brad Steiger's dreams are filled with snake worshippers, the end of the world and his daughter, Kelly... Each night the nightmares are more intense as he searches London for Kelly, who's missing. Neither her classmates nor her landlord has seen her in weeks. The sinister air of the dreams convinces Brad that Kelly is in danger and time is running out on her rescue! Brad hires a private investigator that discovers Kelly is part of Ouroboros, a snake worshipping cult led by Professor Jonathan Clay. When the investigator dies under suspicious circumstances, Brad turns to cult expert, Marcus Valentine, and Scotland Yard's Declan Healy in his desperation. As the three men race against time chasing down clues, one thing is clear: the cult is preparing for a momentous event, shrouded in secrecy and the supernatural. Marcus finds an ex-cult member who, under hypnosis, reveals Kelly is alive, but the cult is on the move. Everyone and everything in its path is in imminent danger. No matter how close the three men come to Ouroboros, Jonathan and his slippery shapeshifters elude them. An unexpected source helps Brad and Marcus find the cult, but it may be too little, too late. Now, Brad, Marcus and Jonathan are on a collision course with destiny that may signal the end of the world!
