It certainly is. Jane (Meryl Streep), meets her ex-husband (Alec Baldwin) ten years at their son's graduation ceremony, and sparks fly. They start having a lusty affair, flab and cellulite and all and love it, unknown to their three children and Jake's young wife. The "affair" continues and Streep is thrilled that she is now the other woman to the other woman who had caused their divorce. Their affair has its ups and downs though. Streep is also seeing her architect Adam (Steve Martins), another divorcee, and her situation with Jake complicates things a bit. So after hot and cute romps in hotels, secret dates at their homes, marijuana and drinking binges, the others eventually get to know - Adam, Jake's wife and the three children. Jake leaves his younger wife and moves in with Jane but who will Jane choose now - him or Adam?
