Táto séria sleduje dobrodružstvá mladého chlapca a skupiny starších ľudí, ktorí sa spoločne vydávajú na neuveriteľné cesty. Objavujú kúzla a tajomstvá sveta okolo seba, často s humornými a dojemnými výsledkami. Je to príbeh o priateľstve naprieč generáciami a o tom, ako nikdy nie je neskoro na to začať novú kapitolu plnú prekvapení.
Harry's arch-enemy, Gestapo Lil, is causing trouble again. After Harry's aunts and their gang put Lil's slimy accomplice in jail, Lil swore to get revenge... Gestapo Lil and her cronies are after stash of fabulous hidden treasure - and only Harry and his friends are standing in her way...
When Harry's sent to stay with his great-aunts at Lagg hall, he thinks he is in for a really dull time. But Auntie Florrie, Aunt Bridget and their elderly friends aren't quite as Harry expects them to be. Aren't they too old to be driving fast cars and climbing trees?
