Barbara is a typical modern girl - including her excesses. Despite her father's warnings, she decides to go with her best friend Vicki to a summer camp in Crystal Lake, as a way to provoke her rival, who has been organizing everything. This wasn't supposed to go beyond a moment of entertainment and youthful excess - what they didn't expect was that they would help relive a bloody story that occurred years ago. Because if there's one thing the macabre guardian of that place, hates most, there are new intrusers!
