In Pawan Kalyan's OG, the plot involves a power struggle over a port. A cargo container of RDX explosives is required to be smuggled out of a port. Gambheera (Pawan Kalyan) returns to Bombay to help out Satya Dada (Prakash Raj) in securing his hegemony over the port against the evil designs of Omi (Emraan Hashmi).
Incidentally, quite a few important movies in recent years have the container element. Lokesh Kanagaraj's Vikram comes to mind. The central conflict of the plot revolves around Vikram trying to recover or destroy large containers of high-value drugs that belong to the main antagonist, Sandhanam, and his boss, Rolex.
Jr NTR's Devara featured a container/cargo element. The plot is centered around smuggling operations through the sea (the Red Sea) involving "arms smuggling" and "cargo" from merchant ships.
Suriya's Retro featured a cargo element as well. The plot involves a high-stakes "arms deal", which is a cache of smuggled weapons. However, the layered narrative made the cargo element a sub-plot.
Vijay Deverakonda's Kingdom: Its plot is less explicitly focused on a single container. The plot involves the protagonist going undercover to infiltrate a smuggling ring in Sri Lanka that deals in illegal smuggling. But his main aim is to secure his brother.
In the more recent Madharaasi, Sivakarthikeyan's character has to destroy a container full of arms and weapons.
In all of the above movies, the container/cargo is just a hook. The plot obviously doesn't entirely revolve around an object.
