“Australian Adventures with Ledvedik” is the third part of a trilogy about family adventures with Ledvedik, an alien from a parallel world. Maxim, Vladi and Ledvedik meet in Sydney, where Sasha takes part in an international regatta. Charming Karolin, Vladi's cousin, is also here. Maxim falls head over heels in love with her and is looking forward to two awesome weeks. Instead of enjoying their vacation, our friends get involved in a dangerous out-of-this-world adventure. As crazy as this may sound, Vladi convinces them that he is on the trail of a gang of aliens who are about to destroy our earth.
