Marlon Moore is part of Walden Lane Middle School's buddy program. The popular program helps new kids adapt to the school by pairing them up with a buddy. The buddy's job is to help new students by introducing them to friends and showing them around the campus. Marlon takes his job seriously. New kid Robert seems like a cool guy and fits in well with Marlon's crew. But Marlon learns quickly that Robert is a thief. First he steals some food from the local 7-Eleven. The boys think it's a fluke. But then Robert steals from WowTech, a gaming and electronics store. He puts an old PSP into Marlon's backpack, and he steals a high-tech smartphone for himself. Marlon wants to ghost his new buddy, but his sister, Ashley, convinces him that Robert is worth saving.
