Gone baby gone

This was a good thriller with a very difficult and unsuspecting moral twist at the end, which would be futile to disclose...so I won’t. Hmmm, that doesn’t sound like me...basically, kid goes missing, cute boy gets drafted to find her and eventually he does, cops are implicated and the cute boy returns her to her junkie mother even though she was happy with the senior cop that took her to save her from the life of misery and neglect and even though he lost a love of his life in the process. Very sad, very deep, a must see!!! Tiger would love it.
