The teenage improv troupe the IMPosters will kick off its winter season with a two-act show at Alex’s Place on Saturday, Dec. 5, at 8 pm. The first act will consist of short-form improvised games and skits, which include a lot of audience participation. In the second act, the troupe will perform its Chicago-style, theatrical-based long-form improv. Based off a single suggestion, the troupe improvises a one-act half-hour play using the structure of a teen soap opera. Performers include Eva Wilson, Penelope Dutton, Samantha Cassidy, Jake Baird, and Harold Lawry, directed by Donna Swift. Tickets are $11 at the door and $8 in advance from any cast member.
