Attempting to book a flight from New York City back to Germany, he meets a German woman, Lisa, and her young daughter, Alice, who are also trying to return home. After Lisa leaves Alice temporarily in Philip's care, she disappears to deal with a relationship she has recently terminated. Philip and Alice take a flight to Amsterdam on the expectation that they will meet Lisa there, only to find she never arrived to the airport.When Alice is unwilling to stay in the Amsterdam airport alone while Philip leaves, the two decide to return to West Germany where Philip can deliver Alice to her grandmother's home. Unfortunately, Alice can't remember her grandmother's name or address, except that she may live in Wuppertal, the only clue being a photograph of her grandmother's front door with no house number and no one in the shot. After searching through Wuppertal, Alice admits her grandmother doesn't live there and she only wanted them both to stay in Amsterdam. Enraged, Philip turns Alice over to the police, but Alice escapes and returns to him with a new lead that her grandmother lives in Ruhr. The two begin to bond as they travel through Ruhr, and the search comes to an end when the police spot them and inform Philip that Lisa has been found.
Output (English): Question: Why did Philip decide to deliver Alice to her grandmother?, Answer: Because Alice was unwilling to stay in the Amsterdam airport alone while Philip leaves.
