His Phony Son (1918)

For 14 years, merchant Thippe has been paying child support to his dear son, although he has never seen the boy. For the sake of the family legacy, and economic certainty, Thippe decides to meet his offspring. However, something is not quite right. The so-called mother shows few signs of motherly behaviour and the kid has seemingly hit puberty a long time ago – in fact, the boy rather resembles a grown man. (Stumfilm.dk)
