Brightwood

The marriage of Jen and Dan is on the rocks, with Jen seriously considering ending it for good. But when the pair go on a daytime jog in an attempt to hash things out, they soon find themselves running in circles around a pond as the exit trail vanishes and they repeatedly return to the same spot. Being stuck together in an endless loop would be bad enough, but when a silent hooded killer appears and starts tracking them down, the couple must figure out how to survive -- together or apart.
