An unidentified flying object comes across the radar of a low-profile government satellite and is determined to be headed towards a remote town. A top-secret team specifically trained to deal with such alien encounters, known as the Interceptors, are dispatched by the military to handle the situation. If the team is unable to find the life form within 24 hours, military intervention will be taken and the town will take a hit from a nuclear blast so as to protect the world. The only problem is that this particular species of alien life form has the ability to shape-shift.
