CBS announced mid-season schedule changes that include the return of the drama "Flashpoint," the premiere of the mystery event "Harper's Island," the debut of the new game show "Game Show In My Head" and the returns of the Network's reality hits Survivor and The Amazing Race.

"Flashpoint," last summer's top original scripted series, premieres Friday, Jan. 9 (9:00-10:00 PM, ET/PT).

"Flashpoint," starring Enrico Colantoni, Hugh Dillon, Amy Jo Johnson, David Paetkau, Michael Cram, Sergio Di Zio, Ruth Marshall and Mark Taylor, depicts the emotional journey into the tough, risk-filled lives of a group of cops in the Strategic Response Unit (inspired by Toronto's Emergency Task Force).

"Harper's Island," a 13-episode mystery event, premieres Thursday, April 9 (10:00-11:00 PM, ET/PT) and concludes Thursday, July 2 (10:00-11:00 PM, ET/PT). "Harper's Island" is about a group of family and friends who travel to a secluded island for a destination wedding. They've come to laugh... to love... and, though they don't know it... to die. As the wedding festivities begin, friendships are tested and secrets exposed as a murderer claims victims, one by one, transforming the wedding week of fun and celebration into a terrifying struggle for survival. In every episode, someone is killed and every person is a suspect, from the wedding party to the island locals. By the end of the 13 episodes, all questions will be answered, the killer will be revealed and only a few will survive.

"Game Show In My Head," a hidden camera game show from Ashton Kutcher, premieres Saturday, Jan. 3 (8:00-9:00 PM, ET/PT). Ordinary people must perform extraordinary tasks on an unsuspecting public to win up to $50,000. Under the watchful eye of host Joe Rogan, each contestant performs five outrageous, embarrassing and hilarious tasks worth $5,000 each. In a no-holds-barred bonus round, each contestant has the chance to double their money up to $50,000.

The 18th edition of "Survivor" premieres Thursday, Feb. 12 (8:00-9:00 PM, ET/PT) while "The Amazing Race" returns with its 14th edition on Sunday, Feb. 15 (8:00-9:00 PM, ET/PT).
