在这部尼亚加拉，尼亚加拉剧情/爱情片中,Two misfits - Marcy and petty thief Seth meet shop-lifting in their upstate New York hometown. Marcy wants to get a hold of some particular Barbie doll and they take off to Toronto searching for it. Marcy needs pills to take care of her muscle spasms and one of the pharmacists, thinking she is a junkie, shoots her in a leg. They are picked up by lonely widower Walter, who is kind to them.
"Niagra, Niagra" begins quietly in a drugstore in Poughkeepsie, where Marcie, the film's disarming heroine, likes to shoplift. She literally crashes into Seth, a quiet outsider, also on a shoplifting spree. Marcie invites Seth to accompany her to Canada to find a black hairstyling head. They set off in Seth's beat-up station wagon, destined for a toy store in Toronto. While on the road, Marcie confides to Seth that she has Tourette's syndrome, necessitating a series of detours to liquor stories and pharmacies along the roads of upstate New York.
