Abducted 17 years ago, Leia (Ronan) is miraculously found and returned home to her parents Marcy (Nixon) and Glen Dargon (Warshofsky). Having long forgotten her family, after being raised by her captor Benjamin McKay (Isaacs), Leia finds herself unable to connect to those who love her the most. Instead, she yearns for Ben, the only father figure she's ever known, and the safety of the basement she called home most of her life. Marcy resorts to desperate measures to forge a relationship with Leia, allowing her marriage to unravel as a byproduct. With Marcy's increasingly erratic actions echoing those of Ben, Leia is left questioning what it really means to be loved.
