RESCUE ME (Tuesday, 10/9c, FX)
If it weren't for bad luck, this firehouse would have no luck at all. In the emotionally taut (but also darkly funny) season finale, we learn what happened to Tommy Gavin's rookie-firefighter godson Damian, last seen fallen under heavy debris in a warehouse fire. While his own neglected family beckons, Tommy drowns in guilt over the latest mishap. Is there no rescue for these flawed heroes? We'll find out when the show returns for its final season next year, with the finale set to coincide the 10th anniversary of the 9/11 attacks that inspired the series.

Tim McGraw hosts a three-hour spectacle of country star power filmed in June at LP Field in Nashville, an event that signaled the "grand re-opening" of Music City after a devastating flood in May. Among the headliners: Reba McEntire, Rascal Flatts, Carrie Underwood, Keith Urban, the Zac Brown Band and Taylor Swift, whose single "Mine" gets its network TV premiere during the special.

FUTURAMA (Thursday, 10/9c, Comedy Central)
The sci-fi cartoon wraps a triumphant comeback season with its landmark 100th episode, in which Neela leads a revolt of underground mutants who rise up above the "normal" surface dwellers. That's what they get for banishing her to the sewers after Fry inadvertently outs her as an "illegal" alien. Meanwhile, Planet Express is hired to make its 100th delivery. What are the odds that will go well?
