In Scooter Pietsch’s office comedy, Windfall, five disgruntled employees working at a data-processing company lament their tyrannical boss and daydream about the glorious lives they should be living. Stuck in Columbus, Ohio, and finally fed up with that boss, the group pools together their savings to buy into a lottery with a one-billion-dollar jackpot. Naturally, things go very wrong. Windfall premiered in 2016, and now hits Sag Harbor for the summer. The first run was directed by Jason Alexander (Seinfeld’s George), as is this production. —Jensen Davis
