London. 9:00 PM. It is raining. Elena is in a taxi. She sees a glass phone on the seat.
Hello? Is this your phone? You left it in the taxi.
A new message arrives on the screen from a contact named 'Mystery Man'.
I am waiting for you.
Wait. I am not the owner of this phone. I found it.
Oh... I see. I am sorry. I am very lonely in this big city. I wanted to meet a friend tonight. But now... I have no friend and no phone.
Don't be sad! I can help you. Where are you?
Please. Come now. I am here.
