S2E15 Better Off Dead

A physician is on a quest to find a remedy for a childhood syndrome that leads to extreme violence. In an unfortunate turn of events, his daughter becomes infected with the illness due to a mishap involving a contaminated needle. Desperate, he resorts to using a cursed silver syringe to extract the essence from a small gland responsible for aggressive behavior in unwilling sex workers, injecting it into his daughter for a temporary fix. However, this procedure leaves the donors in a state of heightened violence. When one of Micki's friends is captured and forced into the treatment, Micki is also taken and faces the same fate as she searches for her friend.
