A fair point, considering the father happens to be dead! Philip is a successful architect with little or no time for his 16-year-old son. When his own father dies, Philip suddenly realises the pain of having been abandoned years ago. Enter Karl, a charming old rogue who claims to have been a close friend of Philip's dad.
