Sam Foster was the father of Frank Foster and husband of Anne. In September 2011, Sam and Anne travelled from France to Weatherfield in order to meet Frank's fiancée Carla Connor, however the celebrations were cut short when Carla lashed out at his parents and left the Rovers. After an intoxicated Carla ran down Stella Price and crashed Frank's car into Barlow's Bookies, the pair arrived at Weatherfield General to question their son - who was prepared to take the rap for the accident and covered for Carla by stating that he was in the driver's seat when the crash occurred, although they were unsure whether to believe his story.
