In part III of the Cuckoo’s nest, the main event that occurs that acts as a turning point in the book is when the patients decide to take a trip to go fishing.  It allows them to temporarily break free from the demanding clutches of the hospital, where they are being monitored all the time.  Doctor Spivey allows McMurphy and nine other patients to go on the trip, however Bromden is hesitant about going.  McMurphy makes a deal with Bromdem and says he will pay for his ten dollar fee of the fishing trip if Bromdem promises to build his body and get strong enough to lift the control panel in the tub room.  Bromdem goes on the fishing trip along with two imposter “aunts” who are really prostitutes.  While they all are on the boat, they catch big fish and drink together.  The captain of the boat and McMurphy get in a small fistfight, but then they share a drink to make it better.  Billy seems to like one of the prostitutes that have come along on the trip, leading
McMurphy to arrange a date for them on a Saturday night.  This whole fishing trip for McMurphy was a chance to show the nurse that she does not have total control over him, and he doesn’t think of her as the highest authority as he asked Doctor Spivey for permission to go on the trip in the first place.  From the trip, Chief Bromdem also gains more self confidence by bonding and talking more with the patients and getting influence from McMurphy’s bold actions.  McMurphy believes that by bringing in the prostitutes to hang out with the patients, it will make them feel stronger by boosting their sexuality, rather than having it oppressed and neglected like it is in the ward.  Throughout the whole trip and more and more in general, the patients rely on McMurphy to be their leader telling them what is right and what to do next.  Out at see at the fishing trip however, he forces the patients to lead now after he has “taught them well”; they don’t need his help and they can control, run the boat, and catch big fish themselves.  This trip also helps all of the patients develop and mentally improve as they gain more independence, confidence, and hope of reaching their goals and the top of the mountain.
