With a surprise baby on the way, a couple races against the clock to complete the Bucket List they wrote when they first met so they can squeeze in a lifetime’s worth of adventures before bellyflopping into parenthood.

The only thing Arthur and Wren are sure about is each other. But even after ten years together, they hardly feel like adults. They’re living in the same Craigslist-furnished one-bedroom Baltimore apartment that they moved into after graduation. A surprise pregnancy is the last thing either of them expect, and a baby is the last thing they feel ready for.

Wren is desperate for one final adventure before the baby comes. So when they find the Bucket List they made in their early days together, Wren convinces Arthur that they better tick off every item. It’s their last chance to do all the things they wanted to do as wistful teenagers, like spend an entire day in bed, get on the jumbotron at a pro football game, or . . . go skydiving? Is that allowed?

But as their due date gets closer, and the items on their list dwindle, Arthur and Wren find they’ve got more questions than answers. What do they want their life to look like as a family? Do they have what it takes to be parents? And the big one: Are they really meant to be together forever?
