Electrical outlet not working...? - electrical outlets, chain together, recommended

I disconnected and removes a from yesterday, and now the next exit, do not work. There were two son goes in the box and individually sealed and locked before all the cables in the area of security. After some preliminary investigations believe, I know that this exit is part of a series, the other (and any other person, that never works), but the other is closer to the breaker box was. When you have had this issue in the middle of the other two, why the first of the string does not work? Is it necessary to do two cables connected to each other?
