From Scratchpad

In the third installment (filmed in 3-D), Jason acquired his trademark hockey mask, and machete. Jason here kills a group of teenagers and a motorcycle gang who are spending time at a farmhouse near a lake. The only survivor, Chris Higgins, (Dana Kimmel) stops Jason by wounding him with an axe blow to the head. As a result, she goes insane in one of the most surreal endings in the series.
