Brian gets a job writing for a teen magazine. After trailing Meg around for research, he discovers that she has a secret boyfriend who's in jail. When Brian attempts to inform the family of Meg's secret life, it is revealed that her boyfriend has broken out of jail, and has been hiding in the Griffin's house.
Stewie becomes obsessed with Lois after she saves Rupert, though Lois doesn't take to the new Stewie too well, and Peter thinks his doctor is molesting him when he undergoes a prostate exam.
After Peter uses Meg's money to buy himself a tank, she gets a job at the new superstore in town. However, the store puts all the shops in town out of business and sucks up the city's power supply. Elsewhere, Brian and Stewie team up to save the town from the corporate giant.
