The plot might be centered around Naruto finding Kushina's old diary or something that reveals a side of her he never knew. This new knowledge makes him see her in a different light, a more intimidating light. And as he tries to come to terms with this, he has to deal with his fear. For example, he might be afraid that he won't live up to her expectations or that he'll disappoint her in some way.
One possible plot is that Naruto accidentally awakens a memory or power related to Kushina that is so overwhelming and intense that it makes him afraid. He then has to deal with this new - found fear while also trying to understand his mother better. It could also involve him having to face Kushina in some sort of spiritual or dream - like encounter and being terrified.
