The story follows Buck, a sled dog and St. Bernard/Scottish Collie mix as his journey combines unbelievable adventures and happenings that will change his life and the lives of those around him. Buck's story begins in Santa Clara, California, where he lives as a beloved domestic dog free from worries. However, when a gold deposit is discovered in Yukon, Canada, Buck is kidnapped and sold due to the sudden demand for sled dogs. In his new life, Buck is forced to work for companies that show him and his colleagues shockingly little compassion. With no one to save him, Buck is determined to save himself.

Once he escapes into nature and snow, Buck's wild instincts begin to kick in and flourish and Buck sets off on series of daring adventures with other dogs of the Canadian forests and his travel companion, John Thornton. Taking up the role of John Thornton is Harrison Ford who, despite the distinction from his typical choice of role, is one of the most esteemed actors involved in the project. 'Call of the Wild' is directed by Chris Sanders with the guidance of Michael Green and Jack London in character development. 'Call of the Wild' also stars Dan Stevens (as Hal), Karen Gillan (as Mercedes) Omar Sy, Bradley Whitford and Colin Woodell.
