Lou Grant plays a pseudo-Russian dictator trying to make his way back into power after narrowly avoiding death by firing squad. Adm. Nelson has to go to his outlaw yacht to get some microfilm, and the craft blows up, stranding a number of people on the open water.
This is a rather grim and gritty one, with several murders and deaths; really high body count. The shark attack was rather comical. Ed Asner does a very good job of embodying a ruthlessly despicable tyrant. There's some interesting, conflicted relationships among the faux-Russians. The day is won, finally (C'mon--this isn't a spoiler--we know the good guys always win in these things!) not through brute force, but by quiet subterfuge. No one emerges unscathed. It turns out to be truly, and somewhat poignantly, a tale of endurance and survival.
