Plot
Wildlife photographer Pickett Smith is taking photographs of the local flora and fauna as he canoes through a swamp surrounding the island mansion estate of the wealthy and influential Crockett family. Through the swamp are numerous indicators of pollution, which Smith believes are connected to pesticide use on the island plantation. After Clint Crockett accidentally tips over his canoe, he and his sister, Karen escort Smith to a mansion where he meets the entire family. The family's grouchy, wheelchair-using patriarch Jason intends spending the next day enjoying both the Fourth of July and his birthday celebrations uninterrupted. Smith tries to call out with his phone, but it is now dead. Then, Jason sends a man named Grover to get rid of the overpopulating frogs. Smith later discovers Grover's corpse covered in snake bites in a nearby swamp not far from Jason's house. Jason orders him not to mention it to anyone else.
Early next morning, Jason's grandson Michael Martindale sets out to check on a downed power line. Distracted by an impromptu hunting session, he accidentally shoots himself in the calf and is rendered immobile by strange Spanish moss which comes to life and strangles him. Tarantulas descend from branches and bite him to death.
Back at Jason's house, Jason's daughter and Michael's mother Iris sends her other son, Ken, into a greenhouse to collect white daisies for a centerpiece. As he gathers the flowers, dozens of tokay geckos and tegus enter and knock over poison, whose toxic gas asphyxiates Michael. Seeing the danger posed by the animals, Smith suggests that everyone leave the island, but Jason is adamant that nothing will ruin his birthday.
