Baltimore sportscaster Mark ""Flex"" Washington finds his bachelor's paradise disrupted when his feisty 14-year-old daughter, Breanna, comes to live with him full-time. Flex is used to the carefree life of a young single man, complete with junk food, sports and women. Breanna is accustomed to no rules and all fun when she visits her dad for two weeks a year. But when the demands of her mother's new job make it necessary for Breanna to move in with her father for the foreseeable future, Flex must adjust to raising a teenager on a day-to-day basis. In the series premiere, Breanna's jealousy of Flex's date causes her to act out, straining their relationship.

When Breanna finds out that her friends are going to a club for ages (14-18) and figures her father won't mind, she decides to follow them to the club. Meanwhile, Duane is trying to avoid a customer he cheated. When Flex comes home from work and finds his parents there and learns that his daughter Breanna was at a club without any permission, he shows her what it's like to be an adult. Which isn't easy. Meanwhile, Duane ends up at Flex's house with the customer he cheated.

Flex gets his first taste of what it's like to be an overprotective father when, Tracy, Breanna's best friend from Atlanta, comes for a weekend visit and is revealed to be a 16-year-old boy. The situation becomes even more complicated when Breanna discovers that she may have more than friendly feelings for Tracy and seeks out dating advice from Flex's girlfriend, Tonya. Meanwhile, Duane makes a bird-brained attempt to get an autograph from the retiring Cal Ripken Jr.

Flex and Breanna find themselves at loggerheads over where she should go to school. While Breanna is eager to attend a funky public school for the performing arts, Flex prefers that she enroll in a posh private academy. But once he hears her excruciatingly bad singing voice, he agrees to let her audition for the performing arts school.

Flex is dismayed when Breanna tries to recover from her recent heartbreak by taking on the persona of a ""player,"" flirting outrageously and toying with every boy around. But he is even more distressed to discover that she's emulating him.

While Breanna is away on a school ski trip, Flex snoops into her room where he makes a shocking discovery. In alarm, he rushes to the ski resort to put a halt to her shenanigans and to have a long-overdue fatherly talk about the birds and the bees.

Breanna's crush on a handsome football player inspires her to do the unthinkable. Meanwhile, Duane pulls a fast one on Flex, who finds himself in a surprising new sideline.
