Warning: Wikipedia contains spoilers

Together with Tina, a sexy but highly inefficient adoption agency employee, he and his family embark on what turns out to be a tour of the United States: Repeatedly, Mel gets hold of the wrong people. When he is finally face to face with his biological parents it is only to find out that they are ex-cons who, ever since the 1960s, have been hippies producing drugs in their own basement and who had to put him up for adoption because they had to go to jail.

Incorporating, and making fun of, various elements of road movies[?], Flirting with Disaster also takes a light-hearted look at the serious issues of same-sex partnerships, adoption, and drug abuse.
