Mr. Boo leads a security guard agency with three agents—Michael, Sam and Ricky. While Sam and Ricky transport a cash delivery to a bank, it is robbed. After a series of hair‑raising, comedic chases the team recovers the money, splits the reward, and with Michael and Sam giving their share to Ricky, they go on haphazardly ever after.
