A British fantasy comedy done as a variant of Jack And The Beanstalk. A young man heads to Amsterdam to find his father who runs a surf themed smoke shop. After finding his father he finds out his shop is failing due to the shop across the road that takes all the business with their green giant theme. The young man ends up meeting a mysterious homeless man who gives him a magic seed. The seed ends up in the toilet and the next day a massive pot tree takes up the whole store with buds the size of pumpkins. This puts him back in business but soon has the competing store plotting on how to steal the bud and enter it into the Amsterdam Bowl.
This is a light stoner flick mixed with a bit of Time Bandits and Jack The Giant Slayer type themes. It is watchable (better if you're high yourself) and you will laugh a few times. Not for kids though as there is constant joint smoking and coarse language (joint smoking is hard on the throat). All in all not bad and they even throw in a few minutes of animation. There was even a moral or two but I can't remember.
