Tells the quirky and hilarious story of a family of hyenas who live in disguise as humans in suburban Teddington, England. Mr. and Mrs. Bold wear clothes, work regular jobs, and raise two children, Bobby and Betty—who are also hyenas. They're determined to fit in, despite their wild instincts and loud laughs.
 
Things get complicated when their nosy neighbor suspects something strange, and an adventure involving a local wildlife park puts their secret at risk. With clever disguises, silly jokes, and lots of heart, the Bolds try to stay hidden while helping others be true to themselves.
