Hello, Dohliy! (2005)

The outskirts of a big city. A young family: Masha, Dead and Zhora the pug. Masha flies away for three days, leaving Zhora in the care of a Dead Man. For the first time in their short life together, the Dead Man remains at home alone, not yet realizing that the next day, with a frantic doorbell, his life will change significantly, and he will fall out of the usual unhurried reality for three whole days. Meanwhile, Zhora will make an eschatological journey and meet many strange people on his way, on whom his dog's life will depend...
