10 Cloverfield Lane (2016)

After an argument with her boyfriend Ben, Michelle hurriedly packs a suitcase, leaves behind a diamond ring, and departs New Orleans. While driving through rural Louisiana at night Ben calls, begging her to return. The news reports of blackouts in several major cities. Her car is suddenly struck and flips off the road. Awakening in a concrete room, Michelle finds she has an injured leg and is chained to the wall. A man named Howard enters and unchains her. She later unsuccessfully ambushes him, and he explains that there has been a massive attack, perhaps by Russians or Martians, and he had found her wreck and saved her life by bringing her to his underground bunker. He tells a doubtful Michelle that they cannot leave for one or two years because the air is poisoned and everyone outside is dead.

Howard takes Michelle on a tour of the well-stocked bunker he built, which houses a third resident, Emmett, whose left arm is in a sling. Through a viewport, Howard shows her his two decayed pigs outside as evidence of the fallout, but she also sees Howard’s truck, and regains the memory of it forcing her off the road. She privately relays this to Emmett, who dismisses it. He says he came to the bunker voluntarily, which he had helped Howard build, after actually seeing the attack happen and injuring his arm while fighting his way inside.
