Die Diebin und der General (2005)

Because of shoplifting and property damage Jessie Fischer, a single mother with a rather big mouth, is sentenced to charitable work in a nursing home. There she meets Walter Voss, known as the General. The fate of the grumpy pensioner, who was disenfranchised by his adult children and deported to the home, touches her and she decides to fight for him. But when the general's expensive pocket watch disappears, Jessie, already convicted of theft, is suspected. But the general stops by and they both embark on an adventurous journey to the sea.
