Mannu, a cute koala, sneaks into the bag of his owner William, who is on his way to attend the Anzac ceremonies. Willim is carrying a precious medallion that his grandfather sent him as a souvenir from the Gallipoli War. The thieves, who are after the medallion, set off with them. On the ship, as William is sailing around Izmir, a brawl breaks out and Mannu, the thieves and the precious locket fall into the water. When Mannu manages to get ashore, he sets out to find his owner. In this process, he is helped by the stray cat Pala. Mannu's path crosses with thieves once again. This time he is rescued by police officer Ayşe and her dog Minik. On this journey from Australia to Gallipoli, whenever Mannu gets into trouble, an old granny saves him. But the truth is very different from what it seems.
