Tempted (2003)

Workaholic Mike grudgingly minds the kids while his wife, legal assistant Emma Burke, flies to Hawaii with the ashes of Lily, the native who raised her and came to Boston with her. On the minor Hawaiian island, Emma finally gets acquainted (again) with her family and decides to stay, also to help with their flower nursery's legal problems. She also learns that her biological mother is alive and well on the island, but refuses to talk to her now and starts an ill-considered affair with handsome cousin Kala. Mike flies in with the two children, complicating everything further.
