Grainbelt University has one attraction for Dobie Gillis (Bobby Van) - women, especially Pansy Hammer (Debbie Reynolds). Pansy's father (Hanley Stafford), even though and maybe because she says she's in dreamville, does not share her affection for Dobie. An English essay which almost revolutionizes English instruction, and Dobie's role in a chemistry lab explosion convinces Mr. Hammer he is right. Pansy is sent off broken-hearted to an Eastern school, but with the help of Happy Stella Kolawski's (Kathleen Freeman) all-girl band, several hundred students and an enraged police force, Dobie secures Pansy's return to Grainbelt.
