Talk about movie in different way

One beautiful fall morning, all activity in New York's Central Park suddenly stops. Soon, people are cutting their own throats and stabbing themselves to death. Downtown, workers at an office building throw themselves off in a lemming-like mass suicide. In Philadelphia, science teacher Elliot Moore (Mark Wahlberg), his wife Alma (Zooey Deschanel), their best friend Julian (John Leguizamo), and his daughter Jess (Ashlyn Sanchez) all decide to head to the countryside to avoid the city -- and the source of the so-called attack. Soon, rumors begin flying of terrorist involvement, while others think the local nuclear power plant may be responsible. All anyone really knows is that the psychological virus is spreading and no one appears immune... or safe.
