The episode has the newcomer to Alaska very much enjoying the 24 hiur days. He seems to have all sorts of energy and hardly ever sleeps. He does this and that...all the natives tell him that he is under the effect of the long days at midsummer. He doesn't believe them. He just keeps on turning and burning. Then, when the 24 hour days stop (Sometime shortly after midsummer (June 21 of course)), he crashes with vengeance and just sleeps for about a week. I assume that the crash period would be sometime in July maybe
