Augusta “Tucker” Delacroix is perfectly content running a successful oil field supply company until her brother and business partner, Jim Bob, dies suddenly. Things go from bad to worse when the family's lawyer introduces her to Monique, a beautiful stranger who turns out to be Jim Bob’s mistress and mother of his son. Monique wants Jim Bob's son to be a Delacroix, and Tucker steps up—it’s what family does.
Willow Vernon has never approved of her sister’s affair with a wealthy married man, but when tragedy strikes, Willow assumes care of her nephew. When Tucker demands shared custody rights, Willow’s ready to go to battle. Tucker’s the same kind of irresponsible philanderer as Jim Bob, and she’s not falling for the Delacroix charm like Monique did, no matter how tempting Tucker might be.
Family ties bring Tucker and Willow together, but they could also tear them, and any chance they have at love, apart.
