The two fathers are Anthony Hopkins and Jim Broadbent, Hopkins has left his wife but still cares for his son, and he meets Broadbent at a party as he is crying over the loss of his son, as his wife has taken the son away to live with a lesbian. Hopkins decides to do something about Jim's luckless situation, there are court proceedings and Broadbent wins, but his wife changes her mind and gives up the lesbian friend, and thus they are at least half way reconciled. Also Hopkins is half way reconciled with his wife, a charming woman, who still cares for him. It's a documentary about very mixed feelings, it just exposes relationship problems without really solving them and without really leading anywhere, except to a kind of half-hearted status quo. It is not a very cheerful picture, the environments are as bleak as the film, so you will probably not see this film again. Fathers can't separate from their sons, and neither can their mothers, so obviously the parents should not separate in the first place. That's about all the moral this film has to offer.
