Fire up the VCR and get in a supply of tapes: The broadcast networks are pulling out the stops to get your attention this first full week of ratings sweeps beginning Sunday at 7 when a new version of "Annie" debuts on ABC.

PBS's "Not for Ourselves Alone," a two-night Ken Burns documentary on Susan B. Anthony and Elizabeth Cady Stanton, begins at 8. See Page 6.

At 9, ABC offers the return of "Who Wants to Be a Millionaire" with host Regis Philbin. The game show, a summer hit, is set to air for 15 consecutive days.

Competing against "Millionaire" at 9 are NBC's "The Magical Legend of the Leprechauns" and CBS's "Shake, Rattle & Roll," both two-part specials, and the season premiere of Fox's "The X-Files."

On Saturday, ABC's "Come On Get Happy: The Partridge Family Story" looks at the '70s series that starred Shirley Jones, David Cassidy, Susan Dey and Danny Bonaduce.

See Page 8 for a roundup of this week's special-for-sweeps television movies.

INTIMATE STRANGERS:

UNSEEN LIFE ON EARTH

Tuesday at 8 on PBS

This four-part series begins with an episode called "Tree of Life," describing the quest of scientists who are mapping the human genome to understand how all life is related by tracing it back to Earth's first life forms, tiny microbes that hold the key to our origins. Next week, in "Keepers of the Biosphere," the series looks at microbes that affect the global climate. The third and fourth installments are "Dangerous Friends & Friendship Enemies," detailing the remarkable interaction between microbes and the humans they call home; and "Creators of the Future," a look at new technologies that use microbes to make our planet cleaner, healthier and more bountiful.

NOVA

"Decoding Nazi Secrets"

Tuesday at 9 on PBS

Academics, crossword fanatics, chess champions, mathematicians, Egyptologists and others who were part of Station X, located in an English country mansion, deciphered what the Germans thought was an unbreakable code, Enigma, and helped to turn the tide of World War II. This two-hour special offers a full account of their efforts, with participants describing their work.

LIFE BEYOND EARTH

Wednesday at 8 on MPT, 9 on WETA

This two-hour special from science writer Timothy Ferris sets out to answer two questions: "Are We Alone?" and "Is Anybody Listening?"

The show uses state-of-the-art production effects to picture deep-space galaxies and satellites and planets where life might be found -- not only planet-sized bodies near a star, but also inside satellites of Jupiter and Saturn.

But for Ferris, who produced the Voyager phonograph record, an artifact launched aboard the interstellar spacecraft, it's the second hour that focuses on his personal interest. In that one, he explores whether intelligence might exist beyond Earth.

The show was filmed in widescreen format in Italy, California, Hawaii, Montana and Utah.
