1863, United States of America.
In a convoy heading West with the hope of a better life, Martha Jane’s father is injured. It is she who must drive the family wagon and tend to the horses. The learning curve is tough, yet Martha Jane has never felt so free. And as it’s more practical for riding, she doesn’t hesitate to wear trousers. This is one bold move too many for Abraham, the leader of the convoy.
Wrongfully accused of theft, Martha is forced to flee. Disguised as a boy and in search of proof of her innocence, she discovers a world in the making where her unique personality will assert itself. An adventure full of danger and rich in encounters that, step by step, will reveal the legendary Calamity Jane.
