I don`t realy want to go too far into the plot, except to say that it`s premise is almost inevitable in real life, a routine breakdown in a neuclear power plant spirals because no-one wants to take responsibility. The screenplay is as precise and accurate as a swiss timepiece, but it`s the quality of the acting that sucks you in, particularly Jack Lemmon`s, performance. You find yourself mentaly and physicaly responding to what he`s gong through, SO convincing is he. Fonda and Douglass are both beautifuly pitched, and would steal any other film, but at his best, and this is at his best, Lemmon was unparralelled. He is everyman in an impossible situation. The story is tense and exiting, believable and definately not dated. The result is totaly engrosing. Sometimes you want a duvet night with beers or candy floss, and why not. Sometimes you want a duvet night with a glass of wine and someone to hold on to. This is for those nights.
