A new mega shark threatens to destroy humanity. The government creates an exact robotic copy of the shark, either equal to or greater than the original. Now they must fight to the death while people and whole cities get in the way.

Danny and Wheeler, well into their 30s, lack something: Danny feels stuck; he's sour and has driven away his terrific girlfriend. Wheeler chases any skirt he sees for empty sex. When they get in a fight with a tow-truck driver, they choose community service over jail and are assigned to be big brothers - Danny to Augie, a geek who loves to LARP (Live Action Role Play), and Wheeler to Ronnie, a pint-size foul-mouthed kid. After a rocky start, things start to go well until both Danny and Wheeler make big mistakes. Can the two men figure out how to change enough to be role models to the boys?

A final live variety show broadcast via radio becomes a metaphor for the natural order of life. A concept and script by Garrison Keilor uses every natural and technical element of working with a tight and close ensemble producing a weekly show to sooth us and guide us through the natural but difficult transitions of aging, becoming less relevant and then dying as new, young life develops and strengthens during our final "performances." This is a rare film for it's remarkable cast and crew and one wonders how the great Robert Altman was able to gather them all at the same place and time to shoot this film.

A gas is let loose upon the world that kills anyone over 25 years old.
