In this third and final installment of "Paperboy", Danny Summers (Logan Lerman) is off to college studying photojournalism. He leaves behind his girlfriend, Monica (Chloe Grace Moretz) and his family in an effort to get out on his own. Danny joins the student newspaper but little does he know his former girlfriend, Angela (Selena Gomez) is a student writer at the college. Danny attempts to catch up with her but finds out she has moved on and has a new boyfriend named Hal Vicker (Jimmy Tatro). Hal is very protective and does not want Danny anywhere near her. But Danny tries to reconcile their differences against Hal's wishes.
Things change when Martians invade. Parts of California are under attack, including Sunnyville. Danny and Angela realize the ones they love are in harm's way and make their way back home with Hal tagging along. Many go missing and but some are abducted like Monica and Danny's sister, Kathy (Kaya Scoldelario). Sunnyville is under siege and the mayor has the town on lockdown, as are other parts of the world. Danny is the only one who has dealt with these types of supernatural entities before and is confided upon by the President (William Fichtner) to come up with a solution. However this is one scenario he isn't sure he can win. With help from the citizens of Sunnyviile, the U.S. military, and his trusty bicycle, they look to defeat the Martians and save the ones they love.
