Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
Nicholas Cage is a corrupt police lieutenant addicted to drugs and gambling in New Orleans after hurricane Katrina. He walks into a room where police offers are photographing some suspects out of the window and he sees an iguana and a bearded dragon. He asks what the iguanas are doing on his coffee table. The other cop tells him there are no iguanas. Cage assumes that he's hallucinating. We see some extreme close-ups of the lizards with Cage in the background that make us think he's hallucinating, too.
