Secret TV Show Endings You Never Knew Existed

"24" quickly became a phenomenon after it premiered in 2001. The exploits of counterterrorism agent Jack Bauer (Kiefer Sutherland) ran for eight seasons and led to a host of spin-offs like "24: Legacy," "24: Live Another Day," and "24: Japan," among others. But, long before the series reached its apex, it almost went in a different direction. Rather than the secret ending of "24" arriving at the series finale, this alternate version came with the end of the first season.

The finale of season one has Jack in a mad rush to rescue his daughter Kim after she has been abducted and held captive for the second time. Meanwhile, Jack's wife Teri discovers that Nina Meyers is the undercover double agent embedded inside the CTU. Jack succeeds in rescuing Kim, but Teri is shot by Nina in a shocking moment that kills off one of the show's main characters. The secret ending, which was later included in the DVD special features, has Teri knocked unconscious and bound but not killed, with Jack finding and rescuing her in time. This change would have had a massive ripple effect on the entirety of the series that followed. Teri's death was a key moment of character development for Jack and Kim, and her death factored into the plot of the show moving forward.
