Shasta McNasty is a rap/rock band made up of the three slackers Scott, Dennis and Randy. While the guys should spend their days practicing their music, they can usually be found hanging out on Venice Beach, drinking in Captain Verne's Bar or coming up with wacky ideas to make life a little more interesting.

Scotty is involved in a brawl with Verne, an angry little person, and his girlfriend is not too happy about it.

Dennis thinks that his chubby girlfriend will dump him when she loses weight.

Scott convinces Dennis and Randy to spend Halloween watching scary movies with him, but he soon becomes scared as he has a nightmare involving Buster the talking parrot.

Scott attempts to tranform Tina, a clumsy waitress, into a sexy lingerie model. She has trouble finding a job when they realise that she looks exactly the same as Victoria's Secret model Suzanne Lanza. Dennis tries to help out, and lands himself a job in the process.

Dennis convinces Randy and Scott to come on his road trip to Las Vegas following the sequence of his free coupon book. The trip turns into a disaster when Scott's former high school girlfriend sticks her new boyfriend, a hitman, onto the boys.

When the boys take a trip to the homeless shelter on Thanksgiving, Dennis is reunited with his deadbeat father, Jack. Jack moves in with the boys, but soon they are all sick of him, and try to get him and his stripper girlfriend back together, so he will move back out.

The boys decide to turn Verne into a professional boxer after he gets into a fight with another little person in a club.

As Dennis babysits the landlord's grandchildren, he entertains them with a story involving the boys, Diana and a bed.

When the boys return from Tijuana, they learn that Eduardo, a bull fighter, has stowed away in their trunk in order to find his long-lost fiance. Meanwhile, Dennis joins a big brother programme, but his little brother soon begins copying his every move.

Dennis sells people looks at the rash on his behind in order to collect money to pay the rent.

The band brainstorms new ideas for names, when they dicover they can not use the 'McNasty' in Shasta McNasty. Meanwhile Diana tries to sabotage Scott's latest realtionship after she reveals she has romantic feelings for him.

Diana accidently draws Scott's ex-girlfriend to him, when she attempts to find out more about his past. Meanwhile, Dennis encounters 'perfume withdrawal', as he searches to find his girlfriend the perfect gift for Valentine's Day.

Verne enlists the help of Michelle and Diana when a scam leaves his bank account empty.

Verne bets his arch rival that his less than great Pee-Wee League football team will win a game. Meanwhile, Scott and Randy bribe a cheerleading team to appear, by telling them that a LA Laker cheerleading scout will be in the crowd.

When Diana's boss makes her throw a bachelorette for his fiance, she is convinced by the boys to have it at Captain Verne's Bar, with the boys doing the catering. The boys, however, have other plans as Verne installs a secret two-way mirror and begins charging people to watch the party. The bride-to-be convinces Dennis to bring out the kinky lingerie and the stripper, making it a night none of them will soon forget.

Shasta's performance for a record executive at Captain Verne's Bar is interupted by Scott having to entertain Verne's date's sister, Michelle's unexpected return and Dennis taking experimental psychotropic pills for money.

Dennis decides to go on the show ""Win Ben Stein's Money"" and gets a butt-kicking from Ben himself.

All of the guys each come down with a bad case of the flu, and learn about some of the simpler things in life.

The guys meet Twinkles the clown, and we then see which third of Shasta is frightened of them.

The guys get an insight into what their futures will be like, if they continue on the road they are heading. This makes them wonder if they even want to be in a band anymore.
