ALPHAS
Syfy, 8:00 p.m. ET
Among tonight’s guest stars is a genre favorite: Summer Glau, who made a strong first impression in Joss Whedon’s Firefly, and has starred, or been featured, in sci-fi and fantasy shows ever since. Tonight, she returns as a powerful “Alpha” whom the team is trying to find – and finding it easy. Just follow the trail of fire and devastation.
