CSI: Vegas (Seasons 1–3)

CSI: Vegas (2021) is a CBS crime drama series you can watch online on iFILM — a direct sequel to the original CSI: Crime Scene Investigation, one of the longest-running procedurals in American television. The new core team includes Paula Newsome, Matt Lauria, and Mandeep Dhillon; Jorja Fox and William Petersen return in pivotal roles.

The Las Vegas crime lab is facing an existential crisis. Someone is challenging its foundational evidence, threatening to overturn years of convictions and cast doubt on every case the lab has ever touched. The new team of forensic investigators has to run fresh science on old ground while the lab's reputation crumbles beneath them. Sin City keeps generating new crimes; the past keeps generating new problems.

The series keeps the procedural precision that made the original a global hit and layers in sharper institutional stakes. Fans of the original get their reunion. Newcomers get a thriller about how fragile the machinery of justice really is. Stream all seasons of CSI: Vegas online on iFILM.
