One day, Mario drives(开车) from his house to his mother's house with his dog, Zoe. Because it is his mother's birthday. But his car can't work in the desert(沙漠).
"Who can help me?" Mario says. "No one can help me..."
Zoe looks at Mario and runs away(离开). Mario is not happy about that.
The sun is very hot and it's 40℃ every day. Mario doesn't have water or food.
"It's the last day. I will die(死). I can't meet my mother..."
"Woof! Woof!" "Here! Here! There is a man!" Frank runs to Mario.
"You have a good dog. He finds me and I find you."
"Thanks, my Zoe."
