Erin doesn't have time for a relationship. After six years of late nights and mind-numbing assignments at her job as a marketing executive, she's finally landed the coveted Smithson Jeweler's account-which means her love life will have to wait a little longer. When the actress at the first commercial shoot upsets the director, Erin finds herself cast as the leading lady alongside Jake, a handsome up-and-coming actor who rescued her cat from the streets and stole her heart. Flustered, she walks away from the shoot wearing the diamond ring, and her mom mistakes it for an engagement between Erin and Jake. Both are desperate enough to get their parents off their backs that they just run with the lie. Now Jake and Erin have to figure out how to admit their story is false without hurting their parents or destroying the friendship they've gained with each other.
