End of Oak Street

| MOVIE SPOILERS AHEAD, YOU HAVE BEEN WARNED |

In 1982, aspiring novelist Denise Platt lives on Oak Street in the suburbs with her husband, Greg, their daughter Audrey, their son Brian, and their dog, Starbuck. The couple's marriage is strained: Denise privately contemplates divorce while Greg, having lost his regular job, works secretly as a pizza delivery driver. One day, Denise observes a mysterious plant that suddenly appears in a neighbor's yard. She takes a photo of it to the library, and the librarian Mrs. Valcourt identifies the plant as a species that became extinct millions of years ago. An unidentified pile of animal excrement also appears in another neighbor's yard, while radio broadcasts report increased solar-flare activity. During a storm, Greg returns home from a pizza delivery when a huge white light suddenly engulfs Oak Street, accompanied by a change in atmospheric pressure, and a power outage.

The following morning, Denise and Greg leave their house to search for Starbuck, who has gone missing. They discover that Oak Street is surrounded by a prehistoric landscape, from which dinosaurs emerge and kill people in the neighborhood. Back home, Audrey concludes that the flashes of light were wormholes that transported the entire neighborhood millions of years into the past. That night, Greg reveals he knows Denise is contemplating divorce and admits that he lost his regular job and has been delivering pizzas because he was ashamed to tell her. Meanwhile, Brian sees Starbuck outside his bedroom window and ventures outside to get him with Audrey accompanying him. Denise and Greg then leave in search of their children. Brian and Audrey encounter Jeannette Christiansen, Brian's neighborhood crush, whose parents have been killed by dinosaurs and they take her with them. Elsewhere, Denise and Greg see a flash of light and follow it to a house containing a wormhole. However, they refuse to leave without their children, and the wormhole disappears. A herd of dinosaurs pursue them but they find shelter in a car, reconcile with each other and reunite with the children.

The following morning, an Allosaurus attacks the group and Greg is killed protecting the others. While fleeing, they encounter the wormhole again above Mrs Valcourt's house. The group reaches the roof and learn that the wormhole appears and disappears at regular intervals. Jeannette jumps through it and disappears but when Brian attempts to follow, he misses the opening and falls. A pterosaur grabs him, but Starbuck appears and attacks the creature, saving Brian. The group attempt to take shelter inside Mrs Valcourt's house but it is infested with dinosaurs. Mrs Valcourt emerges from hiding and manages to kill one before being killed by the others. Denise, Audrey, Brian, and Starbuck escape back to the roof and jump into the wormhole.

Returning to 1982, they realize that they have returned to their own neighborhood on the same night Oak Street originally disappeared, approximately twenty minutes before the event. Denise warns Oak Street residents to leave the neighborhood before the white light appears before arranging for Greg to make his next pizza delivery to a bus stop. Greg arrives and is embraced by his family. The white light appears again, engulfing the suburb as Oak Street disappears and is replaced by the prehistoric landscape. Two years later, the military has contained the area while scientists study the prehistoric environment and its wildlife. Denise has published a book titled The End of Oak Street, based on her experiences.
