The plot: Deadpool (Ryan Reynolds), in-between killing anyone he sets his sights on, is contemplating starting a family. Whatever domestic roles may be involved will have to wait, however, as his reconnection with the X-Men leads to him to a young boy named Russell (Julian Dennison), a powerful mutant with the potential for great disaster. As he connects with the young mutant, time-travelling mercenary Cable (Josh Brolin) has arrived in the present to hunt down the one responsible for the death of his family. With multiple threats on his life and others and his anti-social tendencies making his want to start his own superhero team a bit wonky, it's just another day in the life of everyone's favorite Merc.
