Lawyer Wakem takes the mill on the river Floss away from Edward Tulliver (whose ancestors have owned it for 300 years) and becomes the worst enemy of Tulliver's family. When Edward's daughter, Maggie, grows up, she falls in love with Wakem's son Philip. However, her brother Tom (true to the memory of their father) forbids her to meet him again. When she visits her cousin Lucy Deane, Lucy's fiance, Stephen Guest, falls in love with Maggie at first sight, further complicating matters.

A faithful dramatization of Virginia Woolf's novel. A lecturer, his family, the spinster Aunt Lily, an old friend, and a student, Charles Tansley, spend a summer in an isolated house in Cornwall just before World War I. The stern Mr. Ramsay scolds everybody, while Mrs. Ramsay is the linchpin in keeping the family together. Aunt Lily paints, and the family talk about sailing to the lighthouse, but the trip is always postponed.
