There is no one more loved, revered, admired and adored in Riverdale than... Reggie Mantle? Well, at least Reggie doesn't think there's anyone as loved and admired as himself. And his best friend can back that idea up—his best friend, of course, being his dog, Vader. The unstoppable duo is known around town for pulling the funniest pranks, getting the hottest dates and throwing the best parties. And if anyone even dares to compete with them, there is going to be hell to pay. Come take a look at the life of your hero, the handsome, hilarious Reggie Mantle.

There are a set of unspoken rules when it comes to dealing with Reggie Mantle. Rules that, when broken, can easily get you on his bad side. Unfortunately for most of the people Reggie encounters, they don't know these rules. In fact, there's only one person that does—and it isn't a person at all, it's Reggie's devoted Dachshund, Vader. With half of Riverdale High School having committed the mortal sin of ditching a Mantle house party, Archie and Betty's attempts at interfering in Reggie's life, Midge actually pitying Reggie and a friendship request from someone very unexpected, Reggie and Vader are going to have to get a lot smarter about their schemes!
