A technique utilizes a fishing tool and method for retrieving a fish from a downhole location without removal of a downhole completion. The fishing tool comprises a housing and a piston slidably mounted in the housing. Grip legs are engaged with the piston such that movement of the piston in a first direction along the housing moves the grip legs to a disengaged position for receiving the fish. Subsequent movement of the piston in a second direction causes the plurality of grip legs to move to an engaged position with the fish. The grip legs can be moved between the disengaged and engaged positions after the fishing tool is moved through the completion.
