Line Walker (Chinese: 使徒行者 literally "Apostle Walker") is a 2014 Hong Kong crime thriller drama produced by TVB, starring Michael Miu, Charmaine Sheh and Raymond Lam as the main leads, with Sharon Chan, Benz Hui, Elena Kong, Sammy Sum, Oscar Leung and Toby Leung in major supporting roles. It is the first entry in the franchise.

The drama began broadcasting on August 25 to October 3, 2014, on TVB Jade channel during its 9:30–10:30 p.m. timeslot. In 2022, the drama was selected as one of ten classic TVB dramas being honoured for a new joint Youku and TVB programme.

Plot

Set in Hong Kong, the drama follows the lives of Hong Kong Police's CIB undercover police agents who must live a double life in secrecy. Not knowing when they can return to their normal life, they must also endure the constant fear of being uncovered by those they are assigned to infiltrate. However, this time their lives are put in danger when it is discovered that a mole lives within the police force.

Cheuk Hoi (Michael Miu) is a Chief Inspector of Police (CIP) in Hong Kong Police's Criminal Intelligence Bureau (CIB) unit. He is a righteous supervisor that will resort to unofficial tactics in order to restore the identities of his undercover subordinates who have gone missing and deemed by the police department to have strayed to the criminal side. When he finds his friend Hong To Hang, a fellow Superintendent of Police (SP) in the CIB unit, thrown off a building under mysterious circumstances, he learns from Hong's dying words that there are moles within the police force working for the triads. In order to protect the lives of his five undercover agents, Hong has deleted their files from the police database, erasing their identities as police officers. Hong charges Hoi with the task of finding each lost undercover agent, but dies before he can tell Hoi any further information. Remembering Hong's warning against trusting anyone in the police force, Hoi keeps Hong's last words hidden from his superiors. Instead, he sets out on his own to find Hong's five undercover agents.

With clues left behind by Hong, Hoi finds undercover agent Ting Siu Ka (Charmaine Sheh) who fronts as an owner of a foot massage parlor, and assumes his role as her new handler. Siu Ka's only assignment under Hong was to gather intelligence but Hoi assigns her the task of helping him find the other four undercover agents. Siu Ka decides to get close to Sit Ka Keung (Raymond Lam), nicknamed Bao Seed who is part of an illegal gambling gang. He fronts as an ice deliveryman but is actually in charge of collecting unpaid gambling debts. Siu Ka previously clashed with Bao Seed and his partner Muk Sut when they went to her shop to collect a gambling debt but becomes friendly with them because she knows of their connection to a major triad organization.

Meanwhile, Kobe Lin Ho Kan (Sammy Sum), another undercover agent working for Hong, fronted as a crooked stock broker in order to go to prison and get close to triad boss Chum Foon Hei as the last assignment he received from Hong, but Foon Hei soon proved to be a cunning target. Unable to gain any traction with Foon Hei, Kobe believed he had failed his assignment. However upon Kobe's release from prison, Foon Hei asks Kobe to join his organization. In order for Kobe to follow through with his undercover assignment, Kobe sacrifices his relationship with ICAC officer Mok Sin Yan (Sharon Chan), who is unaware that Kobe is an undercover agent.

Yan investigates Hoi because she suspects that he is a dirty cop with connections to the triads because of his fast raise in the police force and all the cases he is assigned to as the Chief inspector gets foiled. With Yan tracking his every single move, it makes things complicated for Hoi to meet up with the undercover agents. In order to keep one step ahead, Hoi bugs Yan's personal belongings and overhears her personal life. Accidentally he discovers the abusive marital life of Yan's older sister Katie Mok Sin Ching (Elena Kong). While helping Katie to escape her abusive life, the two begin to get closer and eventually begin a relationship.

As Siu Ka continues to work with Bao Seed on missions for Foon Hei, she begins to develop feelings for Bao Seed. It is eventually revealed that Bao Seed is another undercover sent out by Hong. As the 3 undercover agents work together with Hoi, they start to suspect their handler is the mole; however, the 4th undercover, Ada (Skye Chan), was revealed and explained to them her relationship with Hong and Hong's intentions.

When Foon Hei's son dies from the karma of his bad deeds, Foon Hei began to change for the better. Hoi begins to suspect Yip Siu-leung (Patrick Tang) as the mole in the police force. Kobe warns Yan to be careful. At first Yan dismisses Kobe's warning as an act of jealousy; however, she decides to investigate on her own and finds evidence to confirm Hoi's suspicions. Siu-leung eventually finds Yan investigating him. Hurt and enraged, he decides to kill Yan who is saved by Kobe when he tackles Siu-leung off the roof of a building.

Development and casting

• The sales presentation clip was filmed in October 2013. The original 57 second clip featured Michael Miu, Charmaine Sheh, Raymond Lam, Sharon Chan, Elena Kong, Sammy Leung and KK Cheung. The sales presentation clip was unveiled on November 7, 2013, for 2014 drama sales pitch.
• Movie king Tony Leung Ka-fai was originally cast in the drama, but had to withdraw due to a rib injury sustained during filming of Horse Play. A whole new script was written as a result.
• Costume fitting was held on February 28, 2014.
• The blessing ceremony took place on February 28, 2014, 2:00 p.m. at Tseung Kwan O TVB City
• Sammy Leung was originally cast to play the role "Lin Ho Kan", but had to withdraw during the middle of filming due to health reasons. Sammy Sum replaced him, while Patrick Tang took on Sammy Sum's original role "Yip Siu Leung". With Sammy Sum taking over the role of "Lin Ho Kan", Sharon Chan had to re-film scenes with Sammy Sum that she had already filmed with Sammy Leung which caused production to be pushed back for a month.
• Joe Ma was rumoured to have been offered the role of "Lin Ho Kan". Once it was confirmed that the role was given to Sammy Sum, Joe released a statement on his Weibo account and stated during an interview with a reporter that he had turned down the role because "it was not fitting" for him. However, producer Man Wai Hung later clarified that he never contacted Joe about the role and did not understand where such a rumour came from.
• On March 18, 2014, while filming a motorcycle scene, Sammy Sum fell and landed on his right hand which resulted to a wrist fracture. Medical attention was required and Sum was admitted to the hospital for surgery on March 21. Filming was delayed by a few weeks while Sum recovered.
• On March 24, 2014, an extended trailer of the drama was previewed at FILMART 2014.
