Katelynn Derengowski

Seven high-school friends begin their Euro-trip at the actual castle of Vlad the Impaler where he supposedly sold his soul to the devil over 500 years earlier, but the decrepit castle's past envelopes them in a bloody ritual.

Two brothers posing as paramedics kidnap their victims and harvest their organs for the black market. That is until they kidnap a woman they find impossible to kill and it turns out she has more power over them than they over her.
