Captain Matthew Hangar leads a group of Mercenaries, ex calvary men, men hardened by war who wish to come to the aid of those innocent and in need of justice. When one of their own becomes severely injured, they seek help and find a lady doctor, Josephine Burkett. Matthew is dubious of her skills but soon finds her capable as well as admirable--not only for her skills but her beauty too.
Josephine respects Matthew for his loyalty to his friend and is aware of what the men are capable of. She suddenly finds herself in need of their services and begs Matthew to help her brother who has been kidnapped. Matthew puts the men to a vote and they agree to help; but when they go to help, they find things are not all what they seem and Josephine, insisting on following them, is in danger as well.
When Matthew finds Josephine is now in the crosshairs herself, he realizes his heart is on the line as well and he must decide if he can risk his and the lives of his men to obtain what love commands.
