Michelle tells the family that her bicycle is missing, so the family starts a search for it. Later on, Danny, Jesse, and Joey have each brought home a bicycle that looks like Michelle's, but it turns out that none of the three bikes belong to Michelle. At the same time, the disappearances of the three bikes is being investigated by Crime Catchers, a neighborhood watch program led by Mrs. Carruthers, who works at the school Michelle goes to. It turns out that Michelle had forgotten that she left her bike at her friend Derek Boyd's house.

Michelle's favorite part of school, the arts program, has been cancelled because of budget cuts. At a PTA meeting, Danny and Joey stand up for the arts program, and Danny nominates Joey for PTA president. His opponent, Mrs. Carruthers, won't give up without a fight, but with the help of Denise's uncle Richard (played by Little Richard), Joey becomes the co-president of the PTA with Mrs. Carruthers, and they decide that the arts program, which is a favorite among a lot of the students, should be brought back to the school.

Michelle thinks it's going to be a big joke when Joey is the substitute in her class.

As Valentine's Day nears, Rebecca thinks Jesse's lost his romantic spark; and Joey has a secret admirer.
