Invasion

In Florida, a hurricane is approaching the small Homestead town and soon the town is hit. There is a complete destruction, and many residents disappear. While looking for her cat, the girl Rose Varon sees lights landing on the water. Her uncle Dave Groves, who believes in aliens and conspiracy theories, go with her to the place where she saw the lights and sees something strange. He returns later and recovers a mysterious skeleton in the water. He shows his finding to his brother-in-law, the park ranger Russell Varon, and he promises Dave to investigate.

Ranger Russell Varon finds a strangely eaten corps nearby the wrecked Ranger station, practically a skeleton, and an unconscious airman in a wetsuit, Paxton, who has mysterious bite-marks in the neck. In hospital, brother-in-law Dave Groves continues elaborating his alien landing theory, photographs Paxton's wounds, like his own, and hears him say "Don't let them in". Russel's ex Dr. Mariel Underlay, who gets bitten by a living suck-organ broken off Paxton's wound, and her present lover, sheriff Tom Underlay, have a hard time trying to calm the local population, now most households are affected by power cuts. Russel's son Jesse Varon minds kid sister Rose at ma's, then brings her over, finding him under the outdoors improvised shower with lover Larkin Groves. When Russel brings Dave back, on crutches, the skeleton is gone from his car trunk; at home Mariel and Tom are picking up the kids, back to her home, where Rose and second 'papa' Tom tell each-other they saw lights fall from the sky into the water. Larkin discovers even Paxton's wife wasn't told about his wounds and death.

Taking a shortcut when getting gas, Jesse Varon and Kira Underlay find a flipped, partially submerged mobile home and dive to investigate. A mysterious light approaches underwater, and while Jesse observes fascinated causes an explosion, which knocks the boy out. Kira fetches Russell; when he rescues Jesse he sees the light. At the hospital, Mariel diagnoses mere glass cuts and gives him her own blood because AB- is short, but it nearly kills him because of a hemoglobin count above normal except in aquatic creatures. Mariel develops an affinity for water, and admits to Jesse something unspecifiable is wrong. Larkin threatens to expose the sheriff unless he helps her explain a military convoy from the town to the Keys; General Turner lies about an Air Force chemical clean-up from a damaged sewage plant, which was closed before the hurricane. Tom shows her, in strict confidence, they're recovering Paxton's crashed plane, using anti-contamination equipment. A jeweler can only tell Dave the lost ring is an ordinary Valentine wedding model.

Underlay might get the quarantine he has requested when Russell discovers that escaped laboratory animals may be responsible for a deadly flu virus that has spread throughout Homestead.

One of Russell's fellow workers has been shot and killed by Underlay, and Russell questions the mysterious circumstances surrounding the shooting death.

After finding an old Cuban refugee who says he lost his family to "the lights," Russell goes fishing to catch one of the mysterious, orange luminescent beings.

After barely surviving a car crash that has left her injured and the fate of her unborn baby uncertain, Larkin is picked up by a man whose suspicious actions cause her to question his motives. Meanwhile, Mariel desperately tries to emotionally reconnect with her son, Jesse.

A baby is abandoned at Russell's ranger station. Underlay locates the mother, Christina, but she vehemently denies that the child is hers.

Larkin learns that Russell has a criminal record and as a juvenile he was suspected of a double murder.

After reading his internet blog about the strange happenings in Homestead, Dave is abducted by a couple, Pria and Healy, who have a vested interest in learning what he knows about the circumstances surrounding the hurricane's aftermath. Meanwhile, Sirk learns the identity of the dead woman found in the bay and tells Sheriff Underlay. Later, Sirk gets his first look at one of the orange, luminescent beings in the water.

Russell finally confronts Mariel about the changes she's undergone since the hurricane.

After a visit to Mariel, Russell finds that Tom has taken the children on a vacation without asking permission. Someone is hiding outside of Mariel's house and is discovered by Russell. Larkin is suspicious of Russell's intentions towards Mariel.

After Tom is shot, he is taken to hospital to recover. While there, he starts to drift between the past and the present, meeting Mariel for the first time with Russell, but he is fully aware that he already loves Mariel, causing him some confusion during the experience.

Russell, Larkin and Dave are in shock after discovering the identity of a mysterious creature that has been lurking around the Varon home.

Curiosity and frustration get the best of Kira as she searches for the truth about her father, Mariel and what is happening to the people of Homestead.

While reluctantly teaming up to catch two armed hybrids who are the run and extremely volatile, Russell and Underlay stumble upon several suspicious migrant workers who have been banished from the rest of their group.

Mariel finds Christine outside the hospital, and Christine forces Mariel to help her with the pregnancy. Mariel tries to contact her husband Tom now that Christine has been found. Also, school starts again, and the students are not all what they seem. Dave finds a boat key and gets Russell to take a trip with him into the lake, expecting to find something in the water, but only to find something much more suspicious...

Russell and Dave discover the island where former CIA operative Eli Szura has been housing special hybrids.

Russell discovers that his job may be in jeopardy because of his investigation of the hybrids.

As the storm rapidly approaches, Russell and Underlay try to uncover where Szura has hidden the hybrids.

Russell and Tom returns to Homestead, while Mariel, Larkin, Jess, Kira and Rose are fleeing to the north. Out of the blue, a tree falls on the road and they are trapped since the tree is heavy. A truck from the National Guard appears and the soldiers offer a ride to them. But Mariel feels that they are hybrids, and they are captives instead. Two hybrid deputies force him to go with them to Russell's home since they are hunting down Sheriff Underlay for killing Deputy Munger. They capture Dave but Lewis helps him to subdue the hybrid deputies.

Pandemonium ensues as the hybrids continue their roundup of the humans during the hurricane, while Underlay and Russell try to put together a rescue plan.
