When a hurricane devastates South Florida, several of the residents of Homestead, a sleepy town on the edge of the Everglades, survive the storm but are inexplicably changed -- they look the same as before, but something is clearly off, and few can explain why. The apparent head of the conspiracy, Sheriff Tom Underlay (William Fichtner), doesn't seem to know too much about the plan. Park Ranger Russell Varon (
Eddie Cibrian) is also trying to uncover the mystery, with help from his pregnant wife Larkin (Lisa Sheridan), an investigative reporter, and her brother Dave (Tyler Labine), a conspiracy nut who finally seems to have gotten one right and is freaked out by his discovery. He was eager to make sure that his wife Mariel (
Kari Matchett) was transformed, yet just as careful to protect his teenage daughter Kira (Alexis Dziena) from going through the same experience. Underlay and Varon are closely linked -- Mariel is Russell's ex-wife and mother to their two children, teenage Jesse (Evan Peters) and the much-younger Rose (Ariel Gade).
