After Paul Dewey's miniature dachshund, Waldi, eats a pot brownie one night and fast-growing marijuana plants start appearing in his backyard, Dewey does what any sensible person would—he starts selling pot. But it doesn't take long until the underachieving stoner runs into problems with rival dealers, cops, ex-girlfriends, and most problematic of all, a bunch of neighborhood kids with strong noses and even stronger entrepreneurial instincts. When Waldi goes missing, Dewey will stop at nothing to get his dog back—unless, like, you've got a joint ready to go, in which case he probably has time for a quick toke or two.
