All it takes to save a life is one phone call . Kidnapped by a group of threatening men led by a mysterious mastermind (Liu Ye), engineer Grace Wong (Barbie Xu) is locked in a tool shed with a broken analog phone, which she repairs just enough to make an outgoing phone call. She's able to make a connection with a mobile phone belonging to Bob (Louis Koo), a harried debt collector who's hurrying to the airport to see off his estranged son. Bob is skeptical of Grace's plea for help, and a passing traffic cop (Nick Cheung) dismisses the call as a prank. But something in Bob's instincts tells him that she's speaking the truth, and he rushes to find Grace's young daughter, only to witness her being kidnapped by the unknown villains. Soon Bob is embroiled in a pulse-pounding race against all odds, with time running out and his mobile phone's battery running down. Can this irresponsible divorced father with a dead-end future become a hero and save the lives of those who depend on him?
