Fast-paced and funny, the series will follow 12-year-old Henry ‘Hank’ Zipzer, a smart and resourceful boy with a unique perspective on the world. Hank has dyslexia, and when problems arise, he deals with them in a way no-one else would – putting him on a direct collision course with his teachers and parents, who don’t seem to appreciate his latest scheme as much as he thought they would... But, Hank always remains positive and convinced that the next big plan will deliver – after all, tomorrow is another day!
There is a school inspector coming round and the school is to be on its best behaviour. Meanwhile, Hank is trying to do a good turn to McKelty but ends up injuring him more. Hank gradually makes friends with him and they bond over McKelty's funny (but slightly rude) caricatures of members of staff. However Hank accidentally hands them in to Adolf and a chase ensues as Hank and McKelty try and get them back. They finally get them back, only for Hank to accidentally push McKelty and his wheelchair down some stairs, injuring him and the School Inspector in the process. Meanwhile Rosa is fed up at the mess in the house and decides to leave all the dishes, hoping someone will get the message.
Mr Rock is put in charge of doing an assembly on marine life, much to the annoyance of Adolf, who wanted to do it in the first place. As Rock pairs Hank up with Anya, Anya reveals that they are no longer an item. Hank didn't even know they were together! Hank then sets out to win back Anya, but Frankie's advice to be cool and distant to Anya backfires terribly and she becomes more interested in McKelty. When it comes to the final assembly, Hanks saves Anya from a huge collapsing prop and all is forgiven, but Anya still has some bad news for Hank. Meanwhile Emily unaccountably finds herself in love with a boy with a floppy fringe and sparkly eyes and she tries to find a scientific explanation for it.
An elite sports centre opens at Westbrook and Hank and a team of no-hopers are forced to take on McKelty's team to try and gain access to it. Emily does not like the idea and decides to do a one-person protest against it, only it does not work as the elite sports centre has power over the students. She gives up when she finds out they are planning to do the same to the science block. Meanwhile, Hank is unhappy when he does not get to go into the sports centre and goes against McKelty in a basketball tournament to show he is just as good as everyone else.
Only Hank Zipzer would think of holding Christmas in the middle of summer and only Hank's family would agree to let him do it. Soon Hank's imagination runs out of control and he's inviting Mr Rock to join the yuletide fun and planning to get a cow to dress up as a reindeer. Will Emily's perfect planning save Hank from another disaster? And can Mr Rock's unexpected guest, Miss Adolf, really save the day?
It's that time of year again - once more Miss Adolf is trying to get victims to sign up for her annual survival camp. With a rock festival being held just a few miles from Miss Adolf's camp, Hank and friends mean to sneak off to see their favourite band. Unfortunately they reckoned without Miss Adolf's favourite snitch, Nick McKelty. Meanwhile, Stan tries to impress Rosa with his spontaneity by sneaking her off to the festival too, while Emily is left at home to teach Papa Pete and his game-loving pals the perils of playing against a super-smart girl.
