这是一部探讨身份和分辨是非的动画，讲述了一个少女和她的两个监护人天使Ava和恶魔Mal不断讨论什么才是真正为女孩好的故事。虽然Ava和Mal很容易被认为是“好”和“恶”，但是这部短片所引发的讨论绝不止于这些，Ava和Mal代表的可能是我们人性之中的善良与缺陷，也可能映射的是父母、社会等在道德层面对我们的“束缚”。

A teenage girl has two guardians, the angel Ava and the demon Mal who act as her conscience. While these two struggle to keep the stubborn punk girl that can't see them safe they are also figuring out their own differences and preconceptions about each other.
