Cuckoo's Nest Part 3

In this the Part they all do break away and they go for a boat ride (fishing trip) I believe this shows the freedom of their minds now. Rached had control over them when they were oblivious to the fact that you can possibly over ride something if you have enough man power. Also this is similar to when moses leads his people to the red sea and basically makes a passage way for them to walk. McMurphy made a beautiful effort by telling the men of the boat that they were doctors going on a fishing trip.
