From the opening scene of the two sisters dressed as the twins from The Shining, you know this is going to be a strange one.

Sisters, September and July are different from the rest of their peers at school, they have a secret language punctuated by whistles and noises and seem to live in another universe from the others and are consequently shunned by their classmates.
Living with their artistic mother who has her own set of quirks, the sisters get by playing games and making their own fun that often entails September making July do odd dares.
September is the more dominant one and is very controlling but also protective of her much shyer younger sister.

Pascale Kann as September Rakhee Thakrar as Sheela and Mia Tharia as July in September Says

There is an atmosphere of danger and dread that weaves its way throughout the film by actress, screenwriter and first time director, Ariane Labed who elicits great performances from her cast, Mia Tharia (July) Pascale Kann (September) and Rakhee Thakrar as their mother, Sheela.

The sense of unease is more than palpable, it is at times visceral. This gothic thriller is not the most pleasant of watches but is interesting nevertheless and evokes a tension and commentary on mental illness and manipulation.
