Yesterday we told you about the stellar premiere of TNT's Good Behavior, but last night, the spotlight shone on TBS's brand new original, Search Party. The show, a dark comedy about a group of four self-absorbed 20-somethings who come together when a former college acquaintance mysteriously disappears, premieres this coming Monday at 11 p.m. ET.

The cast, crew and celebrity guests gathered at New York City's Metrograph theater for a premiere night featuring everything from custom-printed tee-shirts to a performance by singer Grace Mitchell. Check out photos from the premiere below and, even better, watch a sneak peek of the premiere episode below!

NOTE: Search Party is intended for mature audiences.
