Vatertag(2011)

Otto is the proud father of his three children, David, Julia, and Pius. This requires considerable logistical skill, as the three mothers must not know anything about each other. The game of hide-and-seek is about to be exposed when the nanny, Maria, has to go to the hospital. Otto hopes for help from the loner Josef, a bar acquaintance. It's only a matter of time before the house of cards collapses and the mothers discover the well-kept secret.
