This deeply moving, insightful piece is about connection, memories, and the small moments that can change the course of our lives. Over one fateful summer, an unlikely friendship develops between Diana (Linney), a fiercely iconoclastic artist and single mom, and Alice (Hecht), a free-spirited yet naive young housewife. As the Bicentennial is celebrated across the country, these two young women in Ohio navigate motherhood, ambition, and intimacy, and help each other discover their own independence.
It's a new play, so information about it will be limited until they're in performances.
And about "spending that kind of money" - the show is playing Manhattan Theatre Club, which is a non-profit org, and tickets will almost assuredly be available at affordable prices via discounts and services like TKTS and TDF. You'll likely be able to see this show for less than $50.
