Had an idea for a tv show, wondered if anyone would watch it

12 people receive locked briefcases, they come with a key which has a warning engraved onto it. Inside the cases are a series of photos depicting the persons death, presumebly in the future. Also included are a list of dates, called death dates on which the people will die, however, they do not know who is going to die on what day. Some of them attempt to protect themselves, others there loved ones, and others attempt to solve the origin of the cases
