SYNOPSIS
The night commercial pilot Uli Becker retires, his wife Heide dies saying "one of them isn't yours", leaving him wondering which of their kids, which he knows badly having been almost constantly absent, and appears to him as a nagging conscience while he and trusted dog Walter visit them, seeking DNA test material and pondering character similarities. Slick son Thomas seems as unfaithful as (now harlot-client) Uli, even at the bachelor night before his impeding wedding to Jessica. Uli doubts son Christian's manhood as the softy runs the home for his career bitch MD wife and their kids. Homely daughter Bettina is miserable as devoted wife to businessman Folke, host and mother for a bunch of spoiled ingrates, as Uli convinces her, just as he stirs trouble everywhere else, which all culminates in the wedding day finale.
