Weather plays havoc with the 918th in their attempts to disrupt German naval operations based in Hamburg, forcing multiple aborts and reducing accuracy even when they can glimpse the target through overcast skies. Badly needed help arrives in the form of a meteorologist from the States with the expertise to more accurately predict weather conditions at the target. As it turns out, the meteorologist turns out to be a rather attractive woman. The combination of Gallagher's views of the weather as an enemy, his sexist condescension to her despite her abilities, and his overactive libido, threaten to undermine her efforts. Her panicked reaction to air combat doesn't help matters much either.
