A dirty bomb has detonated in Los Angeles and a terrified husband decides to seal himself up in his suburban home and await the return of his working wife in first time director Chris Gorak's tense and topical drama. As the sun rises on another day in Los Angeles, Brad (Rory Cochrane) sends his wife Lexi (Mary McCormack) off to work with a kiss and a smile. When the media begins reporting on the detonation of a bomb within the city limits and a potentially toxic cloud covers the L.A. basin in ash, Brad enlists the aid of nearby handyman Alvaro (Tony Perez) in making his home as airtight as possible while worriedly awaiting the return of his wife. With roads closed, telephone lines jammed, and reports of multiple explosions pouring in from the media, the panic and isolation of the tragedy begins to take its toll on the horrified community. Though announcements over public airwaves ensure that authorities are doing their best to ensure the arrival of help to those in immediate danger, Brad and the rest of the citizens of L.A. soon discover that the explosions were only the beginning of their horrific ordeal.
