What woman would dare make her home at eerie Marshbanks Abbey, perched on a stony hill in remote Northumbria? It is said its owner, the brilliant botanist, Lord Stacks, killed his beautiful bride there ten years earlier.
Unaware of the tales of Lord Stacks' wickedness, Freddie Lambeth comes to live with her guardian, and through his caring blossoms from a plain, shabbily dressed girl to a lovely young woman. Freddie and Lord Stacks come to need each other as his flowers need sunshine, but Stacks cannot allow himself to love her. His own wickedness has destroyed any chance for happiness.
