The plot is centered around two underachieving pot smokers - Silas P. Silas (Method Man) and Jamal King (Redman). When Silas' friend Ivory (Chuck Davis) dies, Silas uses his ashes as fertilizer for a new batch of marijuana. While both are sitting in the parking lot before taking their THC (Testing for Higher Credentials, as opposed to SAT) exams for college, neither is able to smoke their individual marijuana stash without the help of the other. They soon discover that smoking Silas' new batch summons the ghost of the recently deceased Ivory. Ivory gives them the exact test answers and both of them pass with perfect scores.
