The Night Co.

When athletic teen Mari Collingwood opts to hang out with her friend Paige in town rather than spend an evening in with her parents vacationing at the family's remote lake house, it marks the beginning of a night no one is going to forget.

On the eve of her 17th birthday, Mari and her friend Phyllis set off from the family home to attend a rock concert in the city. Attempting to score some drugs along the way, the pair run afoul of a group of vicious crooks, headed up by the sadistic Krug.
