Based on the autobiographical novels of children's author Laura Ingalls Wilder, the beloved 1970s television drama Little House On The Prairie chronicles the trials and tribulations of a loving family on the American frontier during the late 1800s. Centered around farmer Charles Ingalls (Michael Landon), his wife Caroline (Karen Grassle), and their three daughters Mary (Melissa Sue Anderson), Laura (Melissa Gilbert), and Carrie (twins Lindsay and Sidney Greenbush), the series also features a strong supporting cast of characters that make up the town of Walnut Grove, providing a warm and textured portrait of 19th-century frontier life. This collection includes every episode of the family drama's ninth season and is the first season without the presence of Mary (Melissa Sue Anderson) as a regular cast member.
