Bob Wilton (McGregor) is a journalist with aspirations of being so much more. He knows there's a far-off war he could be fighting in. So in order to prove himself to his estranged wife, he leaves his humble moisture farm in search of adventure.

It's a fun film, though! Don't let anything discourage you from giving it a try. Especially if you like laughing at hippies.
