Pineapple Express

In 1937, a military facility is on watch behind a two-way mirror as a soldier, smoking marijuana, reveals what he hates about the army while remaining euphoric. A high-ranking officer immediately closes the project and deems marijuana illegal.

Seventy-one years later, Dale Denton, a 25-year-old process server and habitual marijuana smoker, visits the home of his drug dealer, Saul Silver, to buy marijuana. Saul tells him that he may already know the identity of Dale's next customer, Ted Jones. Dale drives to Ted's house and witnesses Ted and a police officer, Officer Carol Brazier, shoot a man to death. While fleeing the area, Dale leaves behind his roach, which contains a rare strain of marijuana called Pineapple Express. Ted identifies the strain and sends his two henchmen, Budlofsky and Matheson, to a dealer, Red, who tells them that he has only sold the pot to Saul.
