Peter Krinke and Michael McKeown’s “comedic play” begins with a motley assortment of characters crammed into an old-fashioned bomb shelter. The tale of how they got there gets told in flashback and involves naive scientists, corporate greedheads, unscrupulous government officials, beautiful women, and the “cosmetic imperative” to all be as good-looking as possible. The story is embellished with funny faces, unfunny dialects, and both canned and original music. Shrill silliness might have been the result, but it’s not. The ensemble is nothing if not focused, especially laid-back Joshua Hanson, rubber-faced Mandy Paulson, and Erin Rooney as a supermodel turned espionage agent. Their edgy character-based comedy makes for an hour of engaging satire. Through 11/9: Wed 8:30 PM. Breadline Theatre, 1802 W. Berenice, 773-817-5440. $8-$10.
