A much loved romantic comedy-drama from the black-and-white age of Afrikaans film-making that deals with bureaucratic bungling and accidental 'living in sin'. Planning their 25th wedding anniversary, the Van der Merwe couple realise that their marriage certificate is lost. When they go to the relevant government department, they discover that there is no record of their marriage. Because there is no legal proof of their union, the couple has in a sense been living in sin. Magriet will have none of it and moves into a motel - either she must be made an honest woman once and for all, or 25 years of marriage go out of the window. In the meantime, Grandpa arrives with his pet goat in tow, and only his grandson to appreciate him. Between grandson and grandfather, love and marriage certificates are eventually sorted out - while at the same time scaring off an amorous widow with designs on Grandpa.
