When seven teenagers try to get to their last school dance, ONE DAY explodes into a kaleidoscopic adventure through the gritty inner-city streets of Montreal. Bonds of friendship are stretched to their limits as one by one, the characters pit their hopes for the future against the confusing realities of addiction, violence and first love. From innocent anticipation, to crisis, to renewal, these young filmmakers show us that any day can be the ONE DAY that changes you.
