ERIC SAVOYARD, a police inspector whose marriage is on the verge of breaking, is called to a hostage scene.
He frees the hostages, TOM and his grandchildren RACHEL and ALLAN, but, after an exchange of fire, the assailant manages to run away
Later that very night, while walking out home from the police station, Eric meets again with Rachel and Allan but this time chased by two armed men.
Eric rescues the kids only to understand that they really run a great danger. He takes them to the police station to hand them to his superior LIEUTENANT BRANDY.
Lieutenant Brandy starts asking the usual questions but the kids keep silent, saying nothing.
So Lieutenant Brandy decides then to keep the kids for the night.
Eric leaves the police station and drives home.
When Eric stops at a red light, the kids pop up again, saying they escaped from the police station.
Against all odds and under Rachel's supplication, Eric decides not to bring them back to the police station and although knowing it is risky, he takes the kids with him home.
He learns that they come from FARMINGTON in NEW MEXICO, that their mother is dead and that their father left them.
Before disappearing, their mother gave them the nightingale, a mysterious Indian Navajo heirloom, but BURT TASMANY, a rich jeweler and a dangerous gangster, from Farmington, wants it badly.
Using information from the kids, he tries to find out the secret laying behind this weird bird but unexpectedly, this leads him to embark into a dangerous adventure whose stake are now, not only the kids, their grandpa and this golden nightingale, but his family as well.
