Jesus is about a high profile assassin who plans to fake his own death and lay low to avoid the FBI and all the mafia's hitman. He plans to live his life by using the money he got from drugs he stole from the mafia. Somehow, his plan fails and he couldn't get those drugs because they somehow got concealed in a school's wall, with a super strength blackboard blocking it.

He has no choice but to pose as a high school teacher to guard his stash. While he tries to pretend to be an ordinary citizen as much as possible he often gets involved with cases dealing with crimes and criminals. Will his true identity got busted? How long can he tolerate living his life in a normal world?
