Mark Jason Alcala

With the NCIS Season 15 two-week break finally over, fans have a lot to look forward to when the show resumes. For instance, the show will have American Pickers actor Mike Wolfe as a guest star in an episode to be aired in March. For fans who don't mind some mild spoilers, we have the synopsis for the upcoming episode titled, "Keep Your Enemies Closer."

Wolfe will be the trigger for Gibbs (Mark Harmon) and Ducky (David McCallum) to reopen a decade-old cold case. While watching Wolfe on TV, the two NCIS agents will spot him holding a 200-year-old war stick which seems to be linked to the case. After tracking Wolfe down, Gibbs will learn where the stick came from, which results in the reopening of the case.

American Pickers is a long-running reality television series which premiered in January, 2010. The show follows the adventures of Mike Wolfe and Frank Fritz as antique and collectible pickers as they scour around the country to look for various items. The show, which is now in its 18th season, was created by Wolfe and airs on History on Mondays at 9 p.m. E.T.
