Evan's visit to his great aunt Katherine's house turns eventful when he finds a jar marked "Monster Blood". He and his new friend, Andy, decide to try it out, but are horrified to find that it is growing.

This compelling political drama is based on the true story of high-ranking Pentagon official Daniel Ellsberg, who, during the Nixon era, strove to preserve American democracy by leaking top-secret documents to the New York Times and Washington Post. The documents in question would eventually become famous as the Pentagon Papers, which revealed the true reasons for U.S. involvement in Vietnam.
