In an altered timeline of the United States where robots were built so people can use them as they wish, some were built so humans could have help around the house but some were built for pure entertainment after the war. Jackson (Jax) Riley is a 17 year old living with his 18 year old girlfriend Amy Kurza who is a serious mech (Piloted Robot) mechanic. They share their home with Amy's war vet grandpa; Major Jessie Kurza of the Mech Wars. Their happy life is disrupted when someone from their past wants revenge for what happened to him. Then they go on a dangerous journey to find that person, but they might not make it back home alive.
