The assistant enjoys the comfortable living conditions in the villa, but has not been able to receive his salary. A large number of bills came in, but the engineer refused to pay them, leaving his assistant to prevaricate. The Tobler children were treated very differently, from being doted on to being abused. The assistant saw it, but didn't know whether to intervene. Is there a crisis hidden behind the glamorous life in the manor? And where will Joseph go from an unpaid job?
