After many years in captivity, Ada, a young slave girl, attempts to escape from her captors. She kills one of her guards and steals his gold, then desperately runs away from the slums, seeking to journey to the city of Libertad.
As she begins to run towards freedom, however, Ada's hopes are quickly dashed. A trio of slavers catch up to her, cornering her in an alleyway and threatening to put her through hell once more before killing her. Realizing herself that she has no chance of defeating them, Ada closes her eyes, surrendering herself as she braces for her final moments.
But is it not Ada who is fated to die that day.
When Ada opens her eyes, she finds her slavers on the ground, felled in a heartbeat and laying in pools of their own blood. Standing above them is a warrior; a woman brandishing a sword and shield, whose eyes show no pity for the scum she has just slain.
Without hesitation, Ada offers the woman the gold she stole, and begs her to escort Ada to Libertad.
Thus begins the journey of Ada and Martha, two women being pursued by slavers, assassins, and even monsters. Will the two make it to Libertad in one piece? And when the time comes for them to part ways, how will Ada and Martha react?
