After a 20-year hiatus, divorcee Laura Le Crois is forced to return to her home in a wetland in Louisiana after her father Pappy goes missing along with several other locals to briefly take over his wetland tour business. There, she discovers that her ex-husband, zoologist Charles LeBlanc is attempting to buy the wetland for unknown reasons, and is looking for Pappy. After Laura drives him off, she is met by a man named Matt, who will be soon drafted into the Marines. Matt asks Laura to give him, and his girlfriend Mandy a tour of the wetland so he can propose to her later that evening. Laura reluctantly agrees, and the three head off on a small motorboat.
