Sisters Bonnie and Claire have spent their lives estranged. At 16, Claire ran off to New York to pursue a career in acting, leaving her older sister, Bonnie, to care for their aging parents. Forty-five years later, their parents now gone, Claire is forced to move back home with Bonnie, who bitterly resents the intrusion while denying the evidence of her own decline. The sisters' young niece, Zoe, tries to help them while urging reconciliation, but there's a lot of stubborn history blocking the road.

Moving through 10 years, the first act uses a series of minor automotive mishaps to chart Bonnie's ever-diminishing capacities, while the second act follows them in one last attempt to attain the freedoms that are rapidly fading. With most of the action taking place in cars, this play is a literal journey through the practicalities and the pitfalls of aging, agency and admitting when we need someone.
