Deadline:

Gal Gadot has closed a deal to star opposite Dwayne Johnson in Red Notice, the action comedy which Rawson Marshall Thurber is directing from his original script. Universal Pictures won a heated multi-studio bidding battle in February that ended with a green light commitment in the biggest package deal so far this year. Red Notice will begin shooting April 2019 in Europe and Universal will release the film worldwide June 12, 2020.
No real details on the plot - just that Dwayne's making a shitload of money, lots of studios wanted it, and Gal's co-staring.

Here’s the best we’ve got:

The film’s log line is being kept under wraps, but it is described as a globe-trotting, action-comedy, heist thriller designed as a three-hander between Johnson, Gadot and another male star who’ll soon be set. Gadot plays a brilliant and mysterious figure in the art world.
