Plot title: Vicious Circle Movie plot: Set on the streets of modern-day Venice Beach, Vicious Circle is a tragic punk rock Latino love story; a raw, edgy, teenage Romeo and Juliet with a murder mystery twist. We first see 18-year-old RJ (skateboard star, Paul Rodriguez Jr.) running through the streets of LA with a blood stained shirt and a gun in his backpack, leaving us to wonder, "What happened?" An artist and skater with a heart of gold, R.J. dreams of moving to New York City to pursue his dream of creating comic books. His hand-made sketchbook demonstrates his unique talent and acts as a portal between fantasy and reality. A strong influence of the game of chess from RJ's incarcerated father permeates his art and life; RJ lives by the rules of the game and knows the repercussions of one bad move. Soon, RJ meets Angel (Emily Rios), a rebellious singer in a local teenage punk band. Their unexpected story of true love causes the tides to turn in both lives, and RJ reveals a secret that could cost the life of his new love. My question: How old was R.J?
A:
