In 1 hour – 99 years we follow two young people who have entered into a "Sighe", a temporary marriage practice in Iran. Both Sahab and Maryam are surprisingly open and honest about the topic and show us the pros and cons. A heated discussion between Sahab and his mother illustrates there are very different views on the issue, even within one family. While Sahab believes Sighe is a good opportunity for young people, his mother finds it a hypocritical and unacceptable practice. Maryam, a divorced woman with a young son, shows that a temporary marriage is sometimes the only way to stay off the street in a country where there is hardly any social support system. The documentary also presents a Mullah in the Southern suburbs of Tehran who legalizes temporary marriages, and a matchmaker in Iran’s religious centre Qom. 1 hour – 99 years provides an insight into the lives of people and shows the way old religious practices like Sighe are being used in an attempt to solve contemporary problems.
