I'm going to ruin Up in Smoke as that's their popular film
It's a quest to find the ever-elusive Dave. He wasn't there when Pedro tried to enter his apartment, so Pedro goes on a journey to figure out where Dave went. Assuming that he went south of the border, Pedro gets into his green shaggy van, and starts heading to Mexico. Along the way, he meets singing creatures in a magical forest, and upsets Smokey the Bear when Pedro accidentally sets a tree on fire from a large torch he was holding (he got it from a singing squirrel during one of the film's musical numbers). The movie then becomes a dangerous mission to stop the magical forest from becoming fully engulfed in flames and smoke. Pedro tries to get some help from others, only for them to chase and call him a crazed pyromaniac. Fearing for his life, Pedro gets back into his van, and speeds his way out of the magical forest. As Pedro looks back to see if the coast is clear, he smashes into a building. This turns out to be Dave's apartment, and Dave was, indeed, there all along. Dave sues Pedro, and would later be charged with reckless driving, vehicular assault, and operating while under the influence. This is the kind of stuff that can happen when you go up in smoke, so don't do it!
