Two runaways. Seven outrun soldiers. One military base. The Avengers are called in after two unidentified teenagers repeatedly trespass on military property and somehow evade every attempt to catch them. At first, they're just an annoyance. Then they escape Avengers Tower. Then they outrun the military. Then they disappear completely. As the mystery deepens, the Avengers realize these aren't ordinary runaways. Because nobody becomes this good at vanishing unless they've spent years making sure they're never caught. And the more questions the teenagers refuse to answer, the more dangerous the truth begins to look.
