Amnesia.

When a someone wakes up outside, with no memory of anyone, or anything.. What will it take for them to remember. There seems to be no one, so how will they figure it out ? Will they find people ? Will someone help them ? What would you do ? How will they un-piece the mysterious puzzle and figure it all out ? Or... Will they even do it ? Will they give up ? Or will they figure it out and everything go back to normal ?
