Living full-time in his motorhome with his big-headed cat, Walker heads over to Florida's Space Coast hoping to catch a rocket launch. A lot of other people had the same idea and unfortunately, the only place he can find to park his RV is in a vacant lot behind a Taco Bell. Not to worry, though. Walker's got everything he needs in his motorhome. Waiting for the launch won't be a problem. In fact, he's looking forward to enjoying the downtime. That is, until a mysterious woman shows up asking for RV-related help. She's alone, and after hearing her story, there's no way he can turn her down. But somehow, what starts out as fixing a toilet that won't flush, turns into a high-speed chase involving the FBI, Homeland Security, a dog named Biscuit, and a banana yellow car known as ButterCup. Ride along as Walker and Mango Bob try to unravel this latest mess while dealing with all the weirdness that Florida can throw at them. It's another fun Florida adventure with lots of laughs along the way.
