Here is basically what I get from it - A guy down on his luck is approached by this group who greets him with hospitality, care, open arms, etc. He gladly accepts this because he really is not having a good time with life right now and thinks that this could be the answer he is looking for. Once he starts getting involved he begins to question and the group and eventually realizes this is not what he wants. The he struggles with the idea of leaving due to their brainwashing process and eventually stands on his own two feet knowing that this was a horrible thing. At the end I feel a sense of vengenance by the song When The Walls Come Down although please keep in mind that this is my perception of the story ... asking someone else and they may not feel the same way.
