Episode 21

Criminal Minds revolves around an elite team of FBI profilers who analyze the country's most twisted criminal minds, anticipating their next moves before they strike again.

Family Guy follows Peter Griffin the endearingly ignorant dad, and his hilariously offbeat family of middle-class New Englanders in Quahog, RI. Lois is Peter's wife, a stay-at-home mom with no patience for her family's antics. Then there are their kids: 18-year-old Meg is an outcast at school and the Griffin family punching bag; 13-year-old Chris is a socially awkward teen who doesn't have a clue about the opposite sex; and one-year-old Stewie is a diabolically clever baby whose burgeoning sexuality is very much a work in progress. Rounding out the Griffin household is Brian the family dog and a ladies' man who is one step away from AA.

Resident Alien is a dark, twisted and comedic fish-out-of-water story that follows a crash-landed alien named Harry who, after taking on the identity of a small-town Colorado doctor, slowly begins to wrestle with the moral dilemma of his secret mission on Earth — ultimately asking the question, "Are human beings worth saving?"

After a global pandemic destroys civilization, a hardened survivor takes charge of a 14-year-old girl who may be humanity's last hope.

Some of the world's most incredible engineering projects now lie in ruins. These deserted places are home to extraordinary mysteries and untold secrets, and we revisit them to understand how they were built, and why they were abandoned.

They were once some of the most advanced structures and facilities on the planet, standing at the cutting-edge of design and construction. Today they are abandoned, dangerous, some of them even deadly. From uninhabited cities to empty factories, these long-forgotten engineering marvels are scattered around the globe. Science Channel uncovers why some of the world's most advanced architectural achievements were eventually left behind in the all-new series Mysteries of the Abandoned.

Each of the six, hour-long episodes of Mysteries of the Abandoned features stories behind engineering wonders, why they were built, and the reasons they were eventually left to crumble. Each story recalls the people who originally designed the structure, their historical significance, and why they were ultimately no longer of use. The premiere episode explores California's Goat Canyon Trestle railway, known as the 'Impossible Railroad,' that required the biggest wooden trestle bridge in the world; Ukraine's Duga, the notorious anti-ballistic missile radar, known as the 'Russian Woodpecker,' that still stands in within the Chernobyl Exclusion Zone; and the Grand Goulets Road in the French Alps, an astonishingly narrow and perilous mountain passageway.
