Peter Highman (Robert Downey, Jr.) is a high strung, type A yuppie on his way home from Atlanta to Los Angeles to be present at the birth of his first child, a scheduled C-section, with his wife, Sarah. Once on the plane, Peter learns that Ethan Tremblay (Zach Galifianakis), who had accidentally run his car through his door is sitting behind him in first class. After inadvertently using the words terrorist and bomb, Ethan has Peter shot by an air marshal with a rubber bullet. Both Peter and Ethan are forced off the plane before take-off.
