Three girls Maureen, Caroline and Nora spend their last weekend together on a trip to Canada, before Caroline's wedding. They find themselves involved in a drug-fuelled party and, trying to escape it, are arrested. A guard's assault on Maureen leaves two lawmen dead and the girls are thus on the run with Delgado, a man who desperately wants to cross the borders into the US. None of them have their passports anymore and the consulate is unable to help them. The only way the girls can survive is to kill in their desperate attempts to get back into the US in time for Caroline's wedding.
