Monday Rent Boy begins in Somerset, England, in the mid-1980s, with the winning and heart-warming story of two 13-year-old friends and fellow altar boys, Arthur Barnes and Ernie Castlefrank. Endearing outcasts, they try not to speak of the secret tie that binds them: both boys are routinely preyed on by The Zipper, their nickname for Father Ziperto, the local Catholic priest. Still, they find adventure and release in the mischief they get up to together, as each also tries to survive in other ways.
