I have found the second series of Upright to be struggling. This one was just meandering. It is something you watch without being invested in the characters.
Lucky and Meg are in Cairns. Once again they need to rely on random strangers to find information on Meg's mother. Not appreciating that some other have hidden agendas.
It is Lucky whose luck might be running out. One person from his past appears and he wants revenge on Lucky. He was the one who ended up in jail and Lucky abandoned him.
This was a poor episode, a bit stupid, not funny. The pathos that the first series managed to find is missing here.
