Friends and former college bandmates Elizabeth and Andrew and Zoe have watched one another marry, buy property, and start families, all while trying to hold on to the identities of their youth. But nothing ages them like having to suddenly pass the torch to their own teenage offspring. Back in the band's heyday, Elizabeth put on a snarl over her girl-next-door smile, rich-kid Andrew let his unwashed hair grow past his chin, and beautiful Zoe was the lesbian all the straight women wanted to sleep with. Now nearing 50, they all live within shouting distance in the same Brooklyn neighbourhood and the trappings of the adult world seem to have arrived with ease. But the summer that their children reach maturity, the fabric of the adult lives suddenly begins to unravel, and the secrets and revelations that are finally let loose can never be reclaimed.
