A brave homicide detective finds herself ensnared in a dangerous web of corruption after immersing herself in the realm of sexual fetish videos to track down a slippery serial killer. A deranged individual has been targeting bridesmaids across the city, and Detective Greer English (played by Laura Romeo) is resolute in her mission to bring the perpetrator to justice. As the terror escalates, Detective English zeroes in on Billy Tagg (portrayed by Michael McGovern), a fetish photographer known for his extreme work. However, Billy is not who he seems, and by the time Detective English realizes he has been possessed by an ancient force called “The Tickle Monster,” it might be too late, as she could be laughing her way to an untimely demise.
