Filmmaker Hossein Keshavarz offers a look at life among young people struggling against the constraints of life in an Islamic state in this independent drama. Dawood (Ahmad Akbarzadeh) has just returned to Tehran after some time away; he meets and falls for Katherine (Sara Esfahani), but while her feelings for him are mutual, they can't find a place where they can make love in peace. Dawood's sister Katie (Tahereh Azadi) is a free-spirited young woman who is involved with a handsome man; however, she's not sure what to do about the fact he's married. Mahsa (Maryam Mousavi) is a talented singer who dreams of a career in pop music, but struggles against a Fundamentalist culture that forbids women to perform in public. Hooshang (Rahim Zamani) and Hooman (Bagher Forohar) are a gay couple who are very much in love, but they don't dare reveal their relationship to strangers, while Hooman's family tries to force him into an arranged marriage with a woman. And Massoud (Shahrokh Taslimi) angrily confronts local Muslim fundamentalists after the death of his mother. Dog Sweat was shot in secret to avoid the restrictions imposed upon most filmmakers in Iran; the film was an official selection at the 2010 Los Angeles Film Festival.
