Mermaids (1990) - official trailer

One wild year in the life of 14-year-old Charlotte Flax, when she and her sister Kate move with Mrs. Flax into a sleepy 1960's Massachusetts town. Mrs. Flax is a woman who wears polka-dot dresses and serves hors d'oeuvres for dinner every night, and Kate is a child who basically wants to be a fish. And then there's Charlotte, a young woman of infinite whim and variety. Charlotte's main ambition in life is to become a saint, preferably martyred, though she's Jewish. She's smitten with the shy young caretaker at the convent at the top of the hill. Dann has created a young girl who accepts the unkindness of the mad universe in which she's whirling and takes it on with a savage glee.
