The CW has released an extended trailer for the upcoming back half of the fifth season of “DC’s Legends of Tomorrow,” a clip that begins with a “Star Trek” parody before making fun of other iconic shows.

The series is scheduled to make its return tonight as Sara (Caity Lotz), Constantine (Matt Ryan) and Charlie (Maisie Richardson-Sellers) find themselves in British Columbia searching for another piece of the Loom, but they run into a problem they couldn’t have foreseen.

Meanwhile Zari (Tala Ashe) has been having trouble feeling like herself, so she goes on meditative journey at the suggestion of Behrad (Shayan Sobhian). Meanwhile, Ava (Jes Macallan) volunteers to try and help Rory (Dominic Purcell) with a personal problem.

The series was able to fully complete its current season and so seven full episodes are schedule to air in this block from tonight.
