Memorial Day (1999)

Haunted by an incident from her past, Rachel returns to the scene of the crime to face up to her demons in this terrifying horror film. Little does she know, however, that the past isn't finished with her. Three years ago, while Rachel was having a good time with her friends at a party by the lake, her brother died of unknown causes; her guilt and confusion as to what really happened has plagued her ever since. In a last-ditch attempt to put the memories of that night to rest, Rachel and her friends revisit that lakeside campsite. But what they find there is worse than they ever imagined, and as the group is picked off one by one by an unknown perpetrator bent on revenge, Rachel struggles to discover who is behind the killer's mask--before he turns his attentions to her.
