The Other Side of the Bridge

Arthur and Jake are two brothers, sons of a local farmer, living in the small lakeside town of Struan in Northern Canada. It's the mid-1930s, and another world war is looming. Arthur is solid, dutiful, set to inherit the farm and his father's character. Jake is younger, attractive, mercurial and dangerous to know. A young woman, Laura, comes into the community and tips the balance of sibling rivalry over the edge.
