The Delaneys are fixtures in their community. The parents, Stan and Joy, are the envy of all of their friends. But after 50 years of marriage, they’ve finally sold their famed tennis academy and are ready to start what should be the golden years of their lives. So why are Stan and Joy so miserable? One night a stranger named Savannah knocks on Stan and Joy’s door, bleeding after a fight with her boyfriend. The Delaneys are more than happy to give her the small kindness she sorely needs. If only that was all she wanted. Later, when Joy goes missing, and Savannah is nowhere to be found, the police question the one person who remains: Stan. But for someone who claims to be innocent, he, like many spouses, seems to have a lot to hide.
