Tobias and Agnes are in the end of their middle age. Whatever intense sentimental and sexual relationship may have had up to then, now looks like an old past. The style of their life is nowadays steady and insipid, and in this style they have settled down and adapted, in order to manage to survive. Although, under this superficial calmness, we detect waves of despair and madness, which become clearer with Harry's and Edna's visit, close friends of the couple and of their hysteric daughter Julia. 'A Delicate Balance' gets lost when the three visitors threaten openly the routine secure of their home resulting to all of them being led to a painful conflict.
