Here is official description thx to K-site:
MARTIAN MANHUNTER RETURNS - When Clark (Tom Welling) discovers Lionel (John Glover) threatened to kill him unless Lana (Kristin Kreuk) married Lex (Michael Rosenbaum), he goes after Lionel to silence him once and for all. Lana tells Lex she is leaving him, and Martian Manhunter (guest star Phil Morris) makes a return appearance to help Clark stop Lex, who is trying to find the last wraith from the Phantom Zone in order to use its DNA to power his army of super soldiers. Meanwhile, Lois (Erica Durance) goes to Reeves Dam in search of information about Lex's secret lab and is brutally stabbed by a security guard. Chloe's (Allison Mack) secret power is revealed. Annette O'Toole also stars.

Personally I think the whole "lana dying" thing sucks. She is annoying but its worse to kill her off. Then her shadow will forever be looming Clark and his decisions. Lana is not to Clark what Uncle Ben was to Spiderman.
I agree...sure, I don't really mind that she is going, but it's going to loom over clark for quite some time. Hopefully it won't weigh him down for the whole of the 7th season.
Even with all that I really can not wait to see this episode...although I do hate those 'To be continued...' things.
