Ant Man and The Wasp

Hank and his wife go on business trip to save an atomic bomb from killing millions. Unable to disable it The wife becomes real small and enters in, and is stuck in Quantum time and space. Hank and his daughter, The Wasp, developed a Quantum machine to save her. 

Ant Man who used to be The Wasp's partner in Infinity War, is under house arrest. He plays real elaborate games of adventure with his daughter. After getting a connection with the wife, he made connection with Hank and The Wasp. They shrank him and brought him out as he has the knowledge of the mom since he came back from quantum. 

They managed to get the exact coordinates when mom enters the body of the Ant Man to give the code. All this while, the Ghost and Ben tries to stop them because the Ghost, whose dad perished in a Quantum experiment whereas she survived it but now her molecules are stitched back every sec, has only a few days to live so she wants to steal the mom's energy.

The trio is also trying to escape FBI and this dude who's selling arms on the black market. Eventually they did, saved the mom, where she used her Quantum power to heal Eva the Ghost. And Ben/ Ant Man is free from house arrest.

The family of four starts a Quantum leap for a sample of quantum magic, but everyone else except Ben is alive.

They had been blown away into smmitherins because of injuries. Infinity War is next.
