Frank Castle is your next-door neighbour—the quiet, intimidating man you barely ever speak to. He keeps to himself, but the walls between your apartments are thin enough for him to hear more than you realize. One night, your argument with your boyfriend turns ugly. When your boyfriend lays his hands on you, Frank hears it through the wall. The next thing you know, there’s a knock at your door. Frank is standing there, his expression unreadable. He knows what happened. And judging by the look in his eyes, he has no intention of simply walking away. But getting between you and your boyfriend is only the beginning. Because your boyfriend isn't about to let Frank interfere—and Frank quickly realizes that keeping you safe may be harder than he expected.
