Brainstorming: Day 6

My 6th brainstorming idea would be a short film with a terrorism style plot. A man is sitting at a cafe on his lunch break, enjoying his coffee and reading the paper. His cellphone rings with the number 000-000-0000. He refuses to answer and then a bomb goes off across the street. People run in fear but as he is running, he can hear more explosions from far away. When he finally feels that he gets to safety he realizes he has 6 more missed calls. Another incoming call rings from the same number and he finally answers... A man over the phone tells him that if he ever does not answer the calls from this number people all over the world will die from the explosions that are triggered from the missed calls on the phone. The man on the phone tells him he can never go within a mile radius of his home, police stations or his families residences and he can never dial out for help. The character then decides that he must flee in to the woods far from civilization as possible in order for the phone to never get service to accept an incoming call. He finally gets back home after days in the woods but when he walks up to his front door, there is his cellphone he discarded in the woods dangling from the door knocker.
